• Force caching of handler output which actively resists caching

  - by deceze

  I'm trying to force caching of a very obnoxious piece of PHP script which actively tries to resist caching for no good reason by actively setting all the anti-cache headers: Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Content-Type: text/html; charset=UTF-8 Date: Thu, 22 May 2014 08:43:53 GMT Expires: Thu, 19 Nov 1981 08:52:00 GMT Last-Modified: Pragma: no-cache Set-Cookie: ECSESSID=...; path=/ Vary: User-Agent,Accept-Encoding Server: Apache/2.4.6 (Ubuntu) X-Powered-By: PHP/5.5.3-1ubuntu2.3 If at all avoidable I do not want to have to modify this 3rd party piece of code at all and instead just get Apache to cache the page for a while. I'm doing this very selectively to only very specific pages which have no real impact on session cookies or the like, i.e. which do not contain any personalised information. CacheDefaultExpire 600 CacheMinExpire 600 CacheMaxExpire 1800 CacheHeader On CacheDetailHeader On CacheIgnoreHeaders Set-Cookie CacheIgnoreCacheControl On CacheIgnoreNoLastMod On CacheStoreExpired On CacheStoreNoStore On CacheLock On CacheEnable disk /the/script.php Apache is caching the page alright: [cache:debug] AH00698: cache: Key for entity /the/script.php?(null) is http://example.com:80/the/script.php? [cache_disk:debug] AH00709: Recalled cached URL info header http://example.com:80/the/script.php? [cache_disk:debug] AH00720: Recalled headers for URL http://example.com:80/the/script.php? [cache:debug] AH00695: Cached response for /the/script.php isn't fresh. Adding conditional request headers. [cache:debug] AH00750: Adding CACHE_SAVE filter for /the/script.php [cache:debug] AH00751: Adding CACHE_REMOVE_URL filter for /the/script.php [cache:debug] AH00769: cache: Caching url: /the/script.php [cache:debug] AH00770: cache: Removing CACHE_REMOVE_URL filter. [cache_disk:debug] AH00737: commit_entity: Headers and body for URL http://example.com:80/the/script.php? cached. However, it is always insisting that the "cached response isn't fresh" and is never serving the cached version. I guess this has to do with the Expires header, which marks the document as expired (but I don't know whether that's the correct assumption). I've tried to overwrite and unset headers using mod_headers, but this doesn't help; whatever combination I try the cache is not impressed at all. I'm guessing that the order of operation is wrong, and headers are being rewritten after the cache sees them. early header processing doesn't help either. I've experimented with CacheQuickHandler Off and trying to set explicit filter chains, but nothing is helping. But I'm really mostly poking in the dark, as I do not have a lot of experience with configuring Apache filter chains. Is there a straight forward solution for how to cache this obnoxious piece of code?

• Issues With IIS Hosting Two Domains From Same Folder [closed]

  - by Bob Mc

  I have two different domain names that resolve to the same ASP.Net site. Both domains are hosted on the same server, which runs Windows Server 2003 and IIS6. The sites are differentiated in IIS Manager using host headers. However, both of the sites point to the same folder on the local drive for the site's page files. I am occasionally experiencing an ASP.Net error that says "The state information is invalid for this page and might be corrupted." I'm the site developer so I've addressed all the relevant code-related causes for this issue. However, I was wondering whether having two domains/sites sharing the same folder for an ASP.Net application might be causing this intermittent error. Also, is this generally a bad practice? Should I make separate, duplicate folders for each of the domains? Seems like that can become a maintenance headache.

• iis7 compress dynamic content from custom handler

  - by Malloc

  I am having trouble getting dynamic content coming from a custom handler to be compressed by IIS 7. Our handler spits out json data (Content-Type: application/json; charset=utf-8) and responds to url that looks like: domain.com/example.mal/OperationName?Param1=Val1&Param2=Val2 In IIS 6, all we had to do was put the edit the MetaBase.xml and in the IIsCompressionScheme element make sure that the HcScriptFileExtensions attribute had the custom extension 'mal' included in it. Static and Dynamic compression is turned out at the server and website level. I can confirm that normal .aspx pages are compressed correctly. The only content I cannot have compressed is the content coming from the custom handler. I have tried the following configs with no success: <handlers> <add name="MyJsonService" verb="GET,POST" path="*.mal" type="Library.Web.HttpHandlers.MyJsonServiceHandlerFactory, Library.Web" /> </handlers> <httpCompression> <dynamicTypes> <add mimeType="application/json" enabled="true" /> </dynamicTypes> </httpCompression> _ <httpCompression> <dynamicTypes> <add mimeType="application/*" enabled="true" /> </dynamicTypes> </httpCompression> _ <staticContent> <mimeMap fileExtension=".mal" mimeType="application/json" /> </staticContent> <httpCompression> <dynamicTypes> <add mimeType="application/*" enabled="true" /> </dynamicTypes> </httpCompression> Thanks in advance for the help.

• server caching problem on ASP.NET MVC page

  - by Rita

  Hi I have server caching error on ASP.NET MVC Pages. The scenario is like this. I have two applications (1).External Website and (2).Internal Adminsite, both pointing to the same Database. There is one page called EditProfile Page on the External Website that registered customer can update his profile information like Firstname, Lastname and Address…etc. Similarly there is similar functionality on the Internal Adminsite on the page called CustomerProfile Page where the Site Admin can update all these fields. When the user updates the profile information from the Adminsite, those updates are not reflecting back to the Website. Now I tried restarting the Website on IIS and that din’t help. Again I tried both restarting the Website on IIS and opening a new browser, then those updates are reflecting back. I am wondering how I can come out of this caching problem without restarting the site and open a new browser window everytime? Are there any IIS settings that could help? This caching is happening only on couple of tables only and all the updates are showing up in the database. Appreciate your responses. Thanks

• URL Parts available to URL Rewrite Rules

  - by OWScott

  URL Rewrite is a powerful URL rewriting tool available for IIS7 and newer.  Your rewriting options are almost unlimited, giving you the ability to optimize URLs for search engine optimization (SEO), support multiple domain names on a single site, hiding complex paths and much more. URL Rewrite allows you to use any Server Variable as conditions, and with URL Rewrite 2.0, you can also update them on the fly.  To see all variables available to your site, see this post. An understanding of the parts of a complete URL are essential to working with URL Rewrite, so I’ll include the basics here.  Ruslan Yakushev’s configuration reference was my authoritative source for this. Take this URL for example: The URL is http://www.bing.com/search?q=IIS+url+rewrite The parts of the URL are: http(s)://<host>:<port>/<path>?<querystring> Part Example Server Variable http(s) http SERVER_PORT_SECURE or HTTPS = on/off <host> www.bing.com HTTP_HOST <port> Default is 80 SERVER_PORT <path> search The rule pattern in URL Rewrite <path> /search PATH_INFO <querystring> q=IIS+url+rewrite QUERY_STRING entire URL path with querystring /search?q=IIS+url+rewrite REQUEST_URI It’s important to note that /, : and ? aren’t included in some of the server variables. Understanding which slashes are included is important to creating successful rules.

• Test-Drive ASP.NET MVC Review

  - by Ben Griswold

  A few years back I started dallying with test-driven development, but I never fully committed to the practice. This wasn’t because I didn’t believe in the value of TDD; it was more a matter of not completely understanding how to incorporate “test first” into my everyday development. Back in my web forms days, I could point fingers at the framework for my ignorance and laziness. After all, web forms weren’t exactly designed for testability so who could blame me for not embracing TDD in those conditions, right? But when I switched to ASP.NET MVC and quickly found myself fresh out of excuses and it became instantly clear that it was time to get my head around red-green-refactor once and for all or I would regretfully miss out on one of the biggest selling points the new framework had to offer. I have previously written about how I learned ASP.NET MVC. It was primarily hands on learning but I did read a couple of ASP.NET MVC books along the way. The books I read dedicated a chapter or two to TDD and they certainly addressed the benefits of TDD and how MVC was designed with testability in mind, but TDD was merely an afterthought compared to, well, teaching one how to code the model, view and controller. This approach made some sense, and I learned a bunch about MVC from those books, but when it came to TDD the books were just a teaser and an opportunity missed.  But then I got lucky – Jonathan McCracken contacted me and asked if I’d review his book, Test-Drive ASP.NET MVC, and it was just what I needed to get over the TDD hump. As the title suggests, Test-Drive ASP.NET MVC takes a different approach to learning MVC as it focuses on testing right from the very start. McCracken wastes no time and swiftly familiarizes us with the framework by building out a trivial Quote-O-Matic application and then dedicates the better part of his book to testing first – first by explaining TDD and then coding a full-featured Getting Organized application inspired by David Allen’s popular book, Getting Things Done. If you are a learn-by-example kind of coder (like me), you will instantly appreciate and enjoy McCracken’s style – its fast-moving, pragmatic and focused on only the most relevant information required to get you going with ASP.NET MVC and TDD. The book continues with the test-first theme but McCracken moves away from the sample application and incorporates other practical skills like persisting models with NHibernate, leveraging Inversion of Control with the IControllerFactory and building a RESTful web service. What I most appreciated about this section was McCracken’s use of and praise for open source libraries like Rhino Mocks, SQLite and StructureMap (to name just a few) and productivity tools like ReSharper, Web Platform Installer and ASP.NET SQL Server Setup Wizard.  McCracken’s emphasis on real world, pragmatic development was clearly demonstrated in every tool choice, straight-forward code block and developer tip. Whether one is already familiar with the tools/tips or not, McCracken’s thought process is easily understood and appreciated. The final section of the book walks the reader through security and deployment – everything from error handling and logging with ELMAH, to ASP.NET Health Monitoring, to using MSBuild with automated builds, to the deployment  of ASP.NET MVC to various web environments. These chapters, like those prior, offer enough information and explanation to simply help you get the job done.  Do I believe Test-Drive ASP.NET MVC will turn you into an expert MVC developer overnight?  Well, no.  I don’t think any book can make that claim.  If that were possible, I think book list prices would skyrocket!  That said, Test-Drive ASP.NET MVC provides a solid foundation and a unique (and dare I say necessary) approach to learning ASP.NET MVC.  Along the way McCracken shares loads of very practical software development tips and references numerous tools and libraries. The bottom line is it’s a great ASP.NET MVC primer – if you’re new to ASP.NET MVC it’s just what you need to get started.  Do I believe Test-Drive ASP.NET MVC will give you everything you need to start employing TDD in your everyday development?  Well, I used to think that learning TDD required a lot of practice and, if you’re lucky enough, the guidance of a mentor or coach.  I used to think that one couldn’t learn TDD from a book alone. Well, I’m still no pro, but I’m testing first now and Jonathan McCracken and his book, Test-Drive ASP.NET MVC, played a big part in making this happen.  If you are an MVC developer and a TDD newb, Test-Drive ASP.NET MVC is just the book for you.

• A ToDynamic() Extension Method For Fluent Reflection

  - by Dixin

  Recently I needed to demonstrate some code with reflection, but I felt it inconvenient and tedious. To simplify the reflection coding, I created a ToDynamic() extension method. The source code can be downloaded from here. Problem One example for complex reflection is in LINQ to SQL. The DataContext class has a property Privider, and this Provider has an Execute() method, which executes the query expression and returns the result. Assume this Execute() needs to be invoked to query SQL Server database, then the following code will be expected: using (NorthwindDataContext database = new NorthwindDataContext()) { // Constructs the query. IQueryable<Product> query = database.Products.Where(product => product.ProductID > 0) .OrderBy(product => product.ProductName) .Take(2); // Executes the query. Here reflection is required, // because Provider, Execute(), and ReturnValue are not public members. IEnumerable<Product> results = database.Provider.Execute(query.Expression).ReturnValue; // Processes the results. foreach (Product product in results) { Console.WriteLine("{0}, {1}", product.ProductID, product.ProductName); } } Of course, this code cannot compile. And, no one wants to write code like this. Again, this is just an example of complex reflection. using (NorthwindDataContext database = new NorthwindDataContext()) { // Constructs the query. IQueryable<Product> query = database.Products.Where(product => product.ProductID > 0) .OrderBy(product => product.ProductName) .Take(2); // database.Provider PropertyInfo providerProperty = database.GetType().GetProperty( "Provider", BindingFlags.NonPublic | BindingFlags.GetProperty | BindingFlags.Instance); object provider = providerProperty.GetValue(database, null); // database.Provider.Execute(query.Expression) // Here GetMethod() cannot be directly used, // because Execute() is a explicitly implemented interface method. Assembly assembly = Assembly.Load("System.Data.Linq"); Type providerType = assembly.GetTypes().SingleOrDefault( type => type.FullName == "System.Data.Linq.Provider.IProvider"); InterfaceMapping mapping = provider.GetType().GetInterfaceMap(providerType); MethodInfo executeMethod = mapping.InterfaceMethods.Single(method => method.Name == "Execute"); IExecuteResult executeResult = executeMethod.Invoke(provider, new object[] { query.Expression }) as IExecuteResult; // database.Provider.Execute(query.Expression).ReturnValue IEnumerable<Product> results = executeResult.ReturnValue as IEnumerable<Product>; // Processes the results. foreach (Product product in results) { Console.WriteLine("{0}, {1}", product.ProductID, product.ProductName); } } This may be not straight forward enough. So here a solution will implement fluent reflection with a ToDynamic() extension method: IEnumerable<Product> results = database.ToDynamic() // Starts fluent reflection. .Provider.Execute(query.Expression).ReturnValue; C# 4.0 dynamic In this kind of scenarios, it is easy to have dynamic in mind, which enables developer to write whatever code after a dot: using (NorthwindDataContext database = new NorthwindDataContext()) { // Constructs the query. IQueryable<Product> query = database.Products.Where(product => product.ProductID > 0) .OrderBy(product => product.ProductName) .Take(2); // database.Provider dynamic dynamicDatabase = database; dynamic results = dynamicDatabase.Provider.Execute(query).ReturnValue; } This throws a RuntimeBinderException at runtime: 'System.Data.Linq.DataContext.Provider' is inaccessible due to its protection level. Here dynamic is able find the specified member. So the next thing is just writing some custom code to access the found member. .NET 4.0 DynamicObject, and DynamicWrapper<T> Where to put the custom code for dynamic? The answer is DynamicObject’s derived class. I first heard of DynamicObject from Anders Hejlsberg's video in PDC2008. It is very powerful, providing useful virtual methods to be overridden, like: TryGetMember() TrySetMember() TryInvokeMember() etc.  (In 2008 they are called GetMember, SetMember, etc., with different signature.) For example, if dynamicDatabase is a DynamicObject, then the following code: dynamicDatabase.Provider will invoke dynamicDatabase.TryGetMember() to do the actual work, where custom code can be put into. Now create a type to inherit DynamicObject: public class DynamicWrapper<T> : DynamicObject { private readonly bool _isValueType; private readonly Type _type; private T _value; // Not readonly, for value type scenarios. public DynamicWrapper(ref T value) // Uses ref in case of value type. { if (value == null) { throw new ArgumentNullException("value"); } this._value = value; this._type = value.GetType(); this._isValueType = this._type.IsValueType; } public override bool TryGetMember(GetMemberBinder binder, out object result) { // Searches in current type's public and non-public properties. PropertyInfo property = this._type.GetTypeProperty(binder.Name); if (property != null) { result = property.GetValue(this._value, null).ToDynamic(); return true; } // Searches in explicitly implemented properties for interface. MethodInfo method = this._type.GetInterfaceMethod(string.Concat("get_", binder.Name), null); if (method != null) { result = method.Invoke(this._value, null).ToDynamic(); return true; } // Searches in current type's public and non-public fields. FieldInfo field = this._type.GetTypeField(binder.Name); if (field != null) { result = field.GetValue(this._value).ToDynamic(); return true; } // Searches in base type's public and non-public properties. property = this._type.GetBaseProperty(binder.Name); if (property != null) { result = property.GetValue(this._value, null).ToDynamic(); return true; } // Searches in base type's public and non-public fields. field = this._type.GetBaseField(binder.Name); if (field != null) { result = field.GetValue(this._value).ToDynamic(); return true; } // The specified member is not found. result = null; return false; } // Other overridden methods are not listed. } In the above code, GetTypeProperty(), GetInterfaceMethod(), GetTypeField(), GetBaseProperty(), and GetBaseField() are extension methods for Type class. For example: internal static class TypeExtensions { internal static FieldInfo GetBaseField(this Type type, string name) { Type @base = type.BaseType; if (@base == null) { return null; } return @base.GetTypeField(name) ?? @base.GetBaseField(name); } internal static PropertyInfo GetBaseProperty(this Type type, string name) { Type @base = type.BaseType; if (@base == null) { return null; } return @base.GetTypeProperty(name) ?? @base.GetBaseProperty(name); } internal static MethodInfo GetInterfaceMethod(this Type type, string name, params object[] args) { return type.GetInterfaces().Select(type.GetInterfaceMap).SelectMany(mapping => mapping.TargetMethods) .FirstOrDefault( method => method.Name.Split('.').Last().Equals(name, StringComparison.Ordinal) && method.GetParameters().Count() == args.Length && method.GetParameters().Select( (parameter, index) => parameter.ParameterType.IsAssignableFrom(args[index].GetType())).Aggregate( true, (a, b) => a && b)); } internal static FieldInfo GetTypeField(this Type type, string name) { return type.GetFields( BindingFlags.GetField | BindingFlags.Instance | BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic).FirstOrDefault( field => field.Name.Equals(name, StringComparison.Ordinal)); } internal static PropertyInfo GetTypeProperty(this Type type, string name) { return type.GetProperties( BindingFlags.GetProperty | BindingFlags.Instance | BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic).FirstOrDefault( property => property.Name.Equals(name, StringComparison.Ordinal)); } // Other extension methods are not listed. } So now, when invoked, TryGetMember() searches the specified member and invoke it. The code can be written like this: dynamic dynamicDatabase = new DynamicWrapper<NorthwindDataContext>(ref database); dynamic dynamicReturnValue = dynamicDatabase.Provider.Execute(query.Expression).ReturnValue; This greatly simplified reflection. ToDynamic() and fluent reflection To make it even more straight forward, A ToDynamic() method is provided: public static class DynamicWrapperExtensions { public static dynamic ToDynamic<T>(this T value) { return new DynamicWrapper<T>(ref value); } } and a ToStatic() method is provided to unwrap the value: public class DynamicWrapper<T> : DynamicObject { public T ToStatic() { return this._value; } } In the above TryGetMember() method, please notice it does not output the member’s value, but output a wrapped member value (that is, memberValue.ToDynamic()). This is very important to make the reflection fluent. Now the code becomes: IEnumerable<Product> results = database.ToDynamic() // Here starts fluent reflection. .Provider.Execute(query.Expression).ReturnValue .ToStatic(); // Unwraps to get the static value. With the help of TryConvert(): public class DynamicWrapper<T> : DynamicObject { public override bool TryConvert(ConvertBinder binder, out object result) { result = this._value; return true; } } ToStatic() can be omitted: IEnumerable<Product> results = database.ToDynamic() .Provider.Execute(query.Expression).ReturnValue; // Automatically converts to expected static value. Take a look at the reflection code at the beginning of this post again. Now it is much much simplified! Special scenarios In 90% of the scenarios ToDynamic() is enough. But there are some special scenarios. Access static members Using extension method ToDynamic() for accessing static members does not make sense. Instead, DynamicWrapper<T> has a parameterless constructor to handle these scenarios: public class DynamicWrapper<T> : DynamicObject { public DynamicWrapper() // For static. { this._type = typeof(T); this._isValueType = this._type.IsValueType; } } The reflection code should be like this: dynamic wrapper = new DynamicWrapper<StaticClass>(); int value = wrapper._value; int result = wrapper.PrivateMethod(); So accessing static member is also simple, and fluent of course. Change instances of value types Value type is much more complex. The main problem is, value type is copied when passing to a method as a parameter. This is why ref keyword is used for the constructor. That is, if a value type instance is passed to DynamicWrapper<T>, the instance itself will be stored in this._value of DynamicWrapper<T>. Without the ref keyword, when this._value is changed, the value type instance itself does not change. Consider FieldInfo.SetValue(). In the value type scenarios, invoking FieldInfo.SetValue(this._value, value) does not change this._value, because it changes the copy of this._value. I searched the Web and found a solution for setting the value of field: internal static class FieldInfoExtensions { internal static void SetValue<T>(this FieldInfo field, ref T obj, object value) { if (typeof(T).IsValueType) { field.SetValueDirect(__makeref(obj), value); // For value type. } else { field.SetValue(obj, value); // For reference type. } } } Here __makeref is a undocumented keyword of C#. But method invocation has problem. This is the source code of TryInvokeMember(): public override bool TryInvokeMember(InvokeMemberBinder binder, object[] args, out object result) { if (binder == null) { throw new ArgumentNullException("binder"); } MethodInfo method = this._type.GetTypeMethod(binder.Name, args) ?? this._type.GetInterfaceMethod(binder.Name, args) ?? this._type.GetBaseMethod(binder.Name, args); if (method != null) { // Oops! // If the returnValue is a struct, it is copied to heap. object resultValue = method.Invoke(this._value, args); // And result is a wrapper of that copied struct. result = new DynamicWrapper<object>(ref resultValue); return true; } result = null; return false; } If the returned value is of value type, it will definitely copied, because MethodInfo.Invoke() does return object. If changing the value of the result, the copied struct is changed instead of the original struct. And so is the property and index accessing. They are both actually method invocation. For less confusion, setting property and index are not allowed on struct. Conclusions The DynamicWrapper<T> provides a simplified solution for reflection programming. It works for normal classes (reference types), accessing both instance and static members. In most of the scenarios, just remember to invoke ToDynamic() method, and access whatever you want: StaticType result = someValue.ToDynamic()._field.Method().Property[index]; In some special scenarios which requires changing the value of a struct (value type), this DynamicWrapper<T> does not work perfectly. Only changing struct’s field value is supported. The source code can be downloaded from here, including a few unit test code.

• xen 4.1 host priodically dropping network packets of domU

  - by Dyutiman Chakraborty

  I have xen 4.1 Host running on a ubuntu 12.04 LTS Server with ip 153.x.x.54. I have setup 2 VMs on it, namely, "dev.mydomain.com" and "web.mydomain.com" with ips 195.X.X.2 and 195.x.x.3 respectively. For network the VMs connect through xendbr0 (xen-bridge), and can accces the network properly. I can also login to the VMs with ssh with no issue. However when I ping any of the VMs, there is a high amount of periodic packet drop. If I the ping the xen host (dom0) there is no packet drop. Following is a output of "tcpdump | grep ICMP" on dOM0 while I was pinging one of the domU tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type

• Can't run ASP.NET MVC 2 web app on IIS 7.5

  - by Portman

  I'm trying to run an ASP.NET MVC 2 web application under IIS on Windows 7, but I get a 403.14 error. Here are the steps to reproduce: Open Visual Studio 2010 Create a new ASP.NET MVC 2 project called MvcApplication1 Shift+F5 to run the app. You should see http://localhost:{random_port}/ and the page will render correctly. Click on MvcApplication1, and select "Properties". Go to the "Web" section. Select "Use Local IIS Web server" and create a virtual directory. Save. Shift+F5 to run the app. You should see http://localhost/MvcApplication1/ and an IIS error HTTP Error 403.14 - Forbidden The Web server is configured to not list the contents of this directory.. It's clear that for whatever reason, ASP.NET routing is not working correctly. Things I've already thought of and tried: Verified that all IIS features are enabled in "Turn Windows features on or off". Verified that the default website is configured to use .NET 4.0 Reassigned ASP.NET v4 scripmaps via aspnet_regiis -i in the v4.0.30319 directory. Here's the most amazing part - this is on a just-built machine. New copy of Windows 7 x64 Ultimate, clean install of Visual Studio 2010 Premium, no other websites and no other work performed. Anything else I can try?

• MATLAB Builder NE crash apppool on IIS 7.5

  - by Alkersan

  Im developing a web user interface for MATLAB functions with ASP.NET. Ive started with studying demos and stucked with such problem. I created a MyComponent.dll assembly with deploytool from MATLAB 2010a, target framework - 3.5. This component has one function GetKnot() which returns a figure. function df = getKnot() f = figure('Visible', 'off'); knot; df = webfigure(f); close(f); end Then I made simple webapp in visual studio 2008 sp1, with only one page Default.aspx. I added references to MWArray.dll, WebFiguresService.dll and MyComponent.dll. The codeBehind is: using System; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using MyComponent; using MathWorks.MATLAB.NET.WebFigures; namespace MATLAB_WebApplication { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { var myComponentClass = new MyComponentClass(); var x = myComponentClass.getKnot(); //WebFigureControl1.WebFigure = new WebFigure(); } } } When I run this page on Visual Studio`s Development web server - everything is fine, figure works. But when I`m trying to deploy webfigure on my local iis 7.5 which runs on Win7 x32 - iis app pool crashes. There is an entry in System Event Log "A process serving application pool 'Classic .NET AppPool' suffered a fatal communication error with the Windows Process Activation Service. The process id was '3676'. The data field contains the error number 6D000780". This happens when MyComponent is instantiating. What I could forget when moved to IIS? Other examples, like magic square console application, runs perfect, and every matlab component instantiating, but not in IIS environment.

• URL Rewrite – Multiple domains under one site. Part II

  - by OWScott

  I believe I have it … I’ve been meaning to put together the ultimate outgoing rule for hosting multiple domains under one site.  I finally sat down this week and setup a few test cases, and created one rule to rule them all.  In Part I of this two part series, I covered the incoming rule necessary to host a site in a subfolder of a website, while making it appear as if it’s in the root of the site.  Part II won’t work without applying Part I first, so if you haven’t read it, I encourage you to read it now. However, the incoming rule by itself doesn’t address everything.  Here’s the problem … Let’s say that we host www.site2.com in a subfolder called site2, off of masterdomain.com.  This is the same example I used in Part I.   Using an incoming rewrite rule, we are able to make a request to www.site2.com even though the site is really in the /site2 folder.  The gotcha comes with any type of path that ASP.NET generates (I’m sure other scripting technologies could do the same too).  ASP.NET thinks that the path to the root of the site is /site2, but the URL is /.  See the issue?  If ASP.NET generates a path or a redirect for us, it will always add /site2 to the URL.  That results in a path that looks something like www.site2.com/site2.  In Part I, I mentioned that you should add a condition where “{PATH_INFO} ‘does not match’ /site2”.  That allows www.site2.com/site2 and www.site2.com to both function the same.  This allows the site to always work, but if you want to hide /site2 in the URL, you need to take it one step further. One way to address this is in your code.  Ultimately this is the best bet.  Ruslan Yakushev has a great article on a few considerations that you can address in code.  I recommend giving that serious consideration.  Additionally, if you have upgraded to ASP.NET 3.5 SP1 or greater, it takes care of some of the references automatically for you. However, what if you inherit an existing application?  Or you can’t easily go through your existing site and make the code changes?  If this applies to you, read on. That’s where URL Rewrite 2.0 comes in.  With URL Rewrite 2.0, you can create an outgoing rule that will remove the /site2 before the page is sent back to the user.  This means that you can take an existing application, host it in a subfolder of your site, and ensure that the URL never reveals that it’s in a subfolder. Performance Considerations Performance overhead is something to be mindful of.  These outbound rules aren’t simply changing the server variables.  The first rule I’ll cover below needs to parse the HTML body and pull out the path (i.e. /site2) on the way through.  This will add overhead, possibly significant if you have large pages and a busy site.  In other words, your mileage may vary and you may need to test to see the impact that these rules have.  Don’t worry too much though.  For many sites, the performance impact is negligible. So, how do we do it? Creating the Outgoing Rule There are really two things to keep in mind.  First, ASP.NET applications frequently generate a URL that adds the /site2 back into the URL.  In addition to URLs, they can be in form elements, img elements and the like.  The goal is to find all of those situations and rewrite it on the way out.  Let’s call this the ‘URL problem’. Second, and similarly, ASP.NET can send a LOCATION redirect that causes a redirect back to another page.  Again, ASP.NET isn’t aware of the different URL and it will add the /site2 to the redirect.  Form Authentication is a good example on when this occurs.  Try to password protect a site running from a subfolder using forms auth and you’ll quickly find that the URL becomes www.site2.com/site2 again.  Let’s term this the ‘redirect problem’. Solving the URL Problem – Outgoing Rule #1 Let’s create a rule that removes the /site2 from any URL.  We want to remove it from relative URLs like /site2/something, or absolute URLs like http://www.site2.com/site2/something.  Most URLs that ASP.NET creates will be relative URLs, but I figure that there may be some applications that piece together a full URL, so we might as well expect that situation. Let’s get started.  First, create a new outbound rule.  You can create the rule within the /site2 folder which will reduce the performance impact of the rule.  Just a reminder that incoming rules for this situation won’t work in a subfolder … but outgoing rules will. Give it a name that makes sense to you, for example “Outgoing – URL paths”. Precondition.  If you place the rule in the subfolder, it will only run for that site and folder, so there isn’t need for a precondition.  Run it for all requests.  If you place it in the root of the site, you may want to create a precondition for HTTP_HOST = ^(www\.)?site2\.com$. For the Match section, there are a few things to consider.  For performance reasons, it’s best to match the least amount of elements that you need to accomplish the task.  For my test cases, I just needed to rewrite the <a /> tag, but you may need to rewrite any number of HTML elements.  Note that as long as you have the exclude /site2 rule in your incoming rule as I described in Part I, some elements that don’t show their URL—like your images—will work without removing the /site2 from them.  That reduces the processing needed for this rule. Leave the “matching scope” at “Response” and choose the elements that you want to change. Set the pattern to “^(?:site2|(.*//[_a-zA-Z0-9-\.]*)?/site2)(.*)”.  Make sure to replace ‘site2’ with your subfolder name in both places.  Yes, I realize this is a pretty messy looking rule, but it handles a few situations.  This rule will handle the following situations correctly: Original Rewritten using {R:1}{R:2} http://www.site2.com/site2/default.aspx http://www.site2.com/default.aspx http://www.site2.com/folder1/site2/default.aspx Won’t rewrite since it’s a sub-sub folder /site2/default.aspx /default.aspx site2/default.aspx /default.aspx /folder1/site2/default.aspx Won’t rewrite since it’s a sub-sub folder. For the conditions section, you can leave that be. Finally, for the rule, set the Action Type to “Rewrite” and set the Value to “{R:1}{R:2}”.  The {R:1} and {R:2} are back references to the sections within parentheses.  In other words, in http://domain.com/site2/something, {R:1} will be http://domain.com and {R:2} will be /something. If you view your rule from your web.config file (or applicationHost.config if it’s a global rule), it should look like this: <rule name="Outgoing - URL paths" enabled="true"> <match filterByTags="A" pattern="^(?:site2|(.*//[_a-zA-Z0-9-\.]*)?/site2)(.*)" /> <action type="Rewrite" value="{R:1}{R:2}" /> </rule> Solving the Redirect Problem Outgoing Rule #2 The second issue that we can run into is with a client-side redirect.  This is triggered by a LOCATION response header that is sent to the client.  Forms authentication is a common example.  To reproduce this, password protect your subfolder and watch how it redirects and adds the subfolder path back in. Notice in my test case the extra paths: http://site2.com/site2/login.aspx?ReturnUrl=%2fsite2%2fdefault.aspx I want to remove /site2 from both the URL and the ReturnUrl querystring value.  For semi-readability, let’s do this in 2 separate rules, one for the URL and one for the querystring. Create a second rule.  As with the previous rule, it can be created in the /site2 subfolder.  In the URL Rewrite wizard, select Outbound rules –> “Blank Rule”. Fill in the following information: Name response_location URL Precondition Don’t set Match: Matching Scope Server Variable Match: Variable Name RESPONSE_LOCATION Match: Pattern ^(?:site2|(.*//[_a-zA-Z0-9-\.]*)?/site2)(.*) Conditions Don’t set Action Type Rewrite Action Properties {R:1}{R:2} It should end up like so: <rule name="response_location URL"> <match serverVariable="RESPONSE_LOCATION" pattern="^(?:site2|(.*//[_a-zA-Z0-9-\.]*)?/site2)(.*)" /> <action type="Rewrite" value="{R:1}{R:2}" /> </rule> Outgoing Rule #3 Outgoing Rule #2 only takes care of the URL path, and not the querystring path.  Let’s create one final rule to take care of the path in the querystring to ensure that ReturnUrl=%2fsite2%2fdefault.aspx gets rewritten to ReturnUrl=%2fdefault.aspx. The %2f is the HTML encoding for forward slash (/). Create a rule like the previous one, but with the following settings: Name response_location querystring Precondition Don’t set Match: Matching Scope Server Variable Match: Variable Name RESPONSE_LOCATION Match: Pattern (.*)%2fsite2(.*) Conditions Don’t set Action Type Rewrite Action Properties {R:1}{R:2} The config should look like this: <rule name="response_location querystring"> <match serverVariable="RESPONSE_LOCATION" pattern="(.*)%2fsite2(.*)" /> <action type="Rewrite" value="{R:1}{R:2}" /> </rule> It’s possible to squeeze the last two rules into one, but it gets kind of confusing so I felt that it’s better to show it as two separate rules. Summary With the rules covered in these two parts, we’re able to have a site in a subfolder and make it appear as if it’s in the root of the site.  Not only that, we can overcome automatic redirecting that is caused by ASP.NET, other scripting technologies, and especially existing applications. Following is an example of the incoming and outgoing rules necessary for a site called www.site2.com hosted in a subfolder called /site2.  Remember that the outgoing rules can be placed in the /site2 folder instead of the in the root of the site. <rewrite> <rules> <rule name="site2.com in a subfolder" enabled="true" stopProcessing="true"> <match url=".*" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false"> <add input="{HTTP_HOST}" pattern="^(www\.)?site2\.com$" /> <add input="{PATH_INFO}" pattern="^/site2($|/)" negate="true" /> </conditions> <action type="Rewrite" url="/site2/{R:0}" /> </rule> </rules> <outboundRules> <rule name="Outgoing - URL paths" enabled="true"> <match filterByTags="A" pattern="^(?:site2|(.*//[_a-zA-Z0-9-\.]*)?/site2)(.*)" /> <action type="Rewrite" value="{R:1}{R:2}" /> </rule> <rule name="response_location URL"> <match serverVariable="RESPONSE_LOCATION" pattern="^(?:site2|(.*//[_a-zA-Z0-9-\.]*)?/site2)(.*)" /> <action type="Rewrite" value="{R:1}{R:2}" /> </rule> <rule name="response_location querystring"> <match serverVariable="RESPONSE_LOCATION" pattern="(.*)%2fsite2(.*)" /> <action type="Rewrite" value="{R:1}{R:2}" /> </rule> </outboundRules> </rewrite> If you run into any situations that aren’t caught by these rules, please let me know so I can update this to be as complete as possible. Happy URL Rewriting!

• HtmlForm.Action and .Net Framework 2.0/3.5 Query

  - by Brian

  Disappointingly, the members page for HtmlForm 2.0 is missing... My research seems to indicate that HtmlForm.Action is a property that was added in .Net Framework 3.5. However, I'm using VS2005 and my reference to System.Web (the namespace HtmlForm is under) is to a .Net Framework 2.0 runtime version. Further, my IIS status information also indicates I am using .Net Framework 2.0, when I force an error on my local IIS and read it. Despite this, I am able to use form1.Action successfully...but only on my local IIS. When I try it on vms and external servers, I get [MissingMethodException: Method not found: 'System.String System.Web.UI.HtmlControls.HtmlForm.get_Action()'.] errors. So, my question: 1) Why does it work on my local IIS? Does the fact that I have the 3.5 framework installed make a difference, here? 2) Why does it not work on other IIS? (I think this is because it's not part of .Net 2.0). I guess I just figure that if something is running on .Net Framework 2.0, the presence of 3.5 should not make a difference. Or maybe there's some other cause for these results.

• Hybrid static/dynamic Google Map

  - by jonathanconway

  Ever noticed that when you go to maps.google.com and do a search (say, car wash), it renders a lot of results (represented by small circles) and a few prominent ones (seen as regular-size pins)? Notice how quickly it does this? From what I can tell from analyzing this in Firebug, much of this is generated on the server and sent to the client as a static image. However, it's still dynamic. You can still zoom in and out, or click on a result and see a dynamic InfoWindow rendered. Google have made the map quick and smooth using static images, while still making it flexible. Is there a way to do this kind of 'pre-loading' with my own Google Map (implemented with the Google Maps API)?

However, for the life of me, i can not find any .net code that is simular to that of my Classic ASP page!!!!! Any help would be great! :o) David

• Classic ASP, ASP.NET, IFrames and response.redirect issue....

  - by Abdullah Ahmed

  A client has an asp page with an iframe. The Iframe loads an asp.net page inside the asp classic page. The ASP.NET page is responsible for connecting to a webservice, displaying some data, and then when the user clicks a button it does a response.redirect another classic asp page. Since the asp.net page is in an iframe, the asp page loads inside the iframe when ideally it should be taking over the entire page. I have tried putting javascript in the final asp page to break out of iframes but it does not seem to fire. I tried doing onClientCLick() on the asp.net page and making it break out of the iframe using the following javascript top.location = self.location.href But since that sets the location it seems to refresh the page , breaks out of the iframe but does not fire the serverside onclick event which would then perform the backend calculations and do response.redirect. Any ideas on how I can make sure that the final asp page does not appear inside the iframe and breaks out of it ?

• ASP.Net 4.0 - Response required in SiteMap building?

  - by Nick Craver

  I'm running into an issue upgrading a project to .Net 4.0...and having trouble finding any reason for the issue (or at least, the change causing it). Given the freshness of 4.0, not a lot of blogs out there for issues yet, so I'm hoping someone here has an idea. Preface: this is a Web Forms application, coming from 3.5 SP1 to 4.0. In the Application_Start event we're iterating through the SiteMap and constructing routes based off data there (prettifying URLs mostly with some utility added), that part isn't failing though...or at least isn't not getting that far. It seems that calling the SiteMap.RootNode (inside application_start) causes 4.0 to eat it, since the XmlSiteMapProvider.GetNodeFromXmlNode method has been changed, looking in reflector you can see it's hitting HttpResponse.ApplyAppPathModifier here: str2 = HttpContext.Current.Response.ApplyAppPathModifier(str2); HttpResponse wasn't used at all in this method in the 2.0 CLR, so what we had worked fine, in 4.0 though, that method is called as a result of this stack: [HttpException (0x80004005): Response is not available in this context.] System.Web.XmlSiteMapProvider.GetNodeFromXmlNode(XmlNode xmlNode, Queue queue) System.Web.XmlSiteMapProvider.ConvertFromXmlNode(Queue queue) System.Web.XmlSiteMapProvider.BuildSiteMap() System.Web.XmlSiteMapProvider.get_RootNode() System.Web.SiteMap.get_RootNode() Since Response isn't available here in 4.0, we get an error. To reproduce this, you can narrow the test case down to this in global: protected void Application_Start(object sender, EventArgs e) { var s = SiteMap.RootNode; //Kaboom! //or just var r = Context.Response; //or var r = HttpContext.Current.Response; //all result in the same "not available" error } Question: Am I missing something obvious here? Or, is there another event added in 4.0 that's recommended for anything related to SiteMap on startup? For anyone curious/willing to help, I've created a very minimal project (a default VS 2010 ASP.Net 4.0 site, all the bells & whistles removed and only a blank sitemap and the Application_Start code added). It's a small 10kb zip available here: http://www.ncraver.com/Test/SiteMapTest.zip Update: Not a great solution, but the current work-around is to do the work in Application_BeginRequest, like this: private static bool routesRegistered = false; protected void Application_BeginRequest(object sender, EventArgs e) { if (!routesRegistered) { Application.Lock(); if (!routesRegistered) RouteManager.RegisterRoutes(RouteTable.Routes); routesRegistered = true; Application.UnLock(); } } I don't like this particularly, feels like an abuse of the event to bypass the issue. Does anyone have at least a better work-around, since the .Net 4 behavior with SiteMap is not likely to change?

• Static Website - Converting to Dynamic, need to import information from database on different host

  - by gvernold

  This seems really complicated to ask about so I hope someone can help: We have a long time running static website held with a hosting company that provide PHP, Ruby-on-Rails and Drupal/Joomla support. A little limited I know but we got reasonably decent search engine rankings and didn't want them to drop. We have two much more recently created sites on another host written in Python/Django. The original site is now too big to handle statically and we want to create a more dynamic site in its place without changing servers/webhosts. The data we want to provide the 'new' dynamic site is from the same database providing the Django sites. What is the best solution to build the new site with? Is it better to create PHP pages that connect to the database on the other host? Ruby-on-rails seems like a very fast development environment not too dissimilar to Django, would we be able to fetch data from the existing databases into a rails site and use similar urls to our old static pages?

• ASP.NET MVC2 and Browser Caching

  - by Dan

  Hi I have a web application that fetches a lot of content via ajax. For example when a user edits some data, the browser will send the changes using an ajax post and then do an ajax get to get fresh content and replace an existing div on the page with that content. This was working just find with MVC1, but in MVC2 I would get inconsistent results. I've found that MVC1 by default included an Expires item in the response headers set to the current time, but in MVC2 the Expires header is missing. This is a problem with some browsers (IE8) actually using the cached version of the ajax get instead of the fresh version. To deal with the problem I created a simple ActionFilterAttribute that sets the reponse cache to NoCache (see below), which works, but it seems kind of sillly to decorate every controller with this attribute. Is there a global way to set this for every controller? Is this a bug in MVC2 and it really should be setting the expires on every ActionResult/view/page? Don't most MVC programs deal with data entry where stale data is a very bad thing? Thanks Dan public class ResponseNoCachingAttribute : ActionFilterAttribute { public override void OnResultExecuted(ResultExecutedContext filterContext) { base.OnResultExecuted(filterContext); filterContext.HttpContext.Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache); } }
