  • Tweaking a few URL validation settings on ASP.NET v4.0

    - by Carlyle Dacosta
    ASP.NET has a few default settings for URLs out of the box. These can be configured quite easily in the web.config file within the  <system.web>/<httpRuntime> configuration section. Some of these are: <httpRuntime maxUrlLength=”<number here>” This number should be an integer value (defaults to 260 characters). The value must be greater than or equal to zero, though obviously small values will lead to an un-useable website. This attribute gates the length of the Url without query string. <httpRuntime maxQueryStringLength=”<number here>”. This number should be an integer value (defaults to 2048 characters). The value must be greater than or equal to zero, though obviously small values will lead to an un-useable website. <httpRuntime requestPathInvalidCharacters=”List of characters you need included in ASP.NETs validation checks” /> By default the characters are “<,>,*,%,&,:,\,?”. However once can easily change this by setting by modifying web.config. Remember, these characters can be specified in a variety of formats. For example, I want the character ‘!’ to be included in ASP.NETs URL validation logic. So I set the following: <httpRuntime requestPathInvalidCharacters=”<,>,*,%,&,:,\,?,!”. A character could also be specified in its xml encoded form. ‘&lt;;’ would mean the ‘<’ sign). I could specify the ‘!’ in its xml encoded unicode format such as requestPathInvalidCharacters=”<,>,*,%,&,:,\,?,$#x0021;” or I could specify it in its unicode encoded form or in the “<,>,*,%,&,:,\,?,%u0021” format. The following settings can be applied at Root Web.Config level, App Web.config level, Folder level or within a location tag: <location path="some path here"> <system.web> <httpRuntime maxUrlLength="" maxQueryStringLength="" requestPathInvalidChars="" /> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } If any of the above settings fail request validation, an Http 400 “Bad Request” HttpException is thrown. These can be easily handled on the Application_Error handler on Global.asax.   Also, a new attribute in <httpRuntime /> called “relaxedUrlToFileSystemMapping” has been added with a default of false. <httpRuntime … relaxedUrlToFileSystemMapping="true|false" /> When the relaxedUrlToFileSystemMapping attribute is set to false inbound Urls still need to be valid NTFS file paths. For example Urls (sans query string) need to be less than 260 characters; no path segment within a Url can use old-style DOS device names (LPT1, COM1, etc…); Urls must be valid Windows file paths. A url like “http://digg.com/http://cnn.com” should work with this attribute set to true (of course a few characters will need to be unblocked by removing them from requestPathInvalidCharacters="" above). Managed configuration for non-NTFS-compliant Urls is determined from the first valid configuration path found when walking up the path segments of the Url. For example, if the request Url is "/foo/bar/baz/<blah>data</blah>", and there is a web.config in the "/foo/bar" directory, then the managed configuration for the request comes from merging the configuration hierarchy to include the web.config from "/foo/bar". The value of the public property HttpRequest.PhysicalPath is set to [physical file path of the application root] + "REQUEST_URL_IS_NOT_A_VALID_FILESYSTEM_PATH". For example, given a request Url like "/foo/bar/baz/<blah>data</blah>", where the application root is "/foo/bar" and the physical file path for that root is "c:\inetpub\wwwroot\foo\bar", then PhysicalPath would be "c:\inetpub\wwwroot\foo\bar\ REQUEST_URL_IS_NOT_A_VALID_FILESYSTEM_PATH".

  • Dissecting ASP.NET Routing

    The ASP.NET Routing framework allows developers to decouple the URL of a resource from the physical file on the web server. Specifically, the developer defines routing rules, which map URL patterns to a class or ASP.NET page that generates the content. For instance, you could create a URL pattern of the form Categories/CategoryName and map it to the ASP.NET page ShowCategoryDetails.aspx; the ShowCategoryDetails.aspx page would display details about the category CategoryName. With such a mapping, users could view category about the Beverages category by visiting www.yoursite.com/Categories/Beverages. In short, ASP.NET Routing allows for readable, SEO-friendly URLs. ASP.NET Routing was first introduced in ASP.NET 3.5 SP1 and was enhanced further in ASP.NET 4.0. ASP.NET Routing is a key component of ASP.NET MVC, but can also be used with Web Forms. Two previous articles here on 4Guys showed how to get started using ASP.NET Routing: Using ASP.NET Routing Without ASP.NET MVC and URL Routing in ASP.NET 4.0. This article aims to explore ASP.NET Routing in greater depth. We'll explore how ASP.NET Routing works underneath the covers to decode a URL pattern and hand it off the the appropriate class or ASP.NET page. Read on to learn more!

  • Configuring .NET Users in IIS 6 (ASP.NET 2.0, Win Server 2003)

    - by Bernhard
    Is it possible in IIS 6 to administrate users as in IIS 7 (e.g. as described here: http://technet.microsoft.com/en-us/library/cc731783%28v=ws.10%29.aspx)? In IIS7 you can define users within the ASP.NET group with click on .NET users and it automatically creates a ms sql server db in background in the website directory. So far I didn't found anything about the issue, most forum questions are about how to migrate asp.net sites from IIS6 to IIS7.

  • prevent domain controller using wpad for windows update

    - by BeowulfNode42
    We have a 2012 domain controller in an environment where we are running a web proxy auto discovery (WPAD) setup for client devices, and that proxy server requires authentication. However windows update does not support proxy servers requiring authentication. So we want to prevent windows update on our servers from using the WPAD proxy settings. On a domain member server we can log in to the local administrator account (not domain admin) and un-tick the the "Auto detect proxy settings" in IE internet options and that fixes the issue on those servers. But a domain controller does not have a local admin account, as that account is the domain admin account. Doing this to the domain admin account on the DC does not prevent it from using WPAD. Our whole purpose of running a proxy server that requires authentication is so we can identify what the users on our session based remote desktop servers are doing on the internet. See this MS KB Article for some info about Windows update and proxy servers "How the Windows Update client determines which proxy server to use to connect to the Windows Update Web site" - http://support.microsoft.com/kb/900935

  • Aruba Wireless Controller 200 and AP70 manual

    - by techie
    I have an Aruba wireless system that is currently in use but there is no documentation from the previous person in charge. I have no manuals or login information for the wireless controllers and APs. I checked the Aruba website and you need to register to access the support information but registration isn't instant and takes several days. I've waited for quite a while now and have tried googling and checking the Aruba forums but have found no indication of a manual. What I really need is the ability to reset the controller and APs so I can access the device with the default username and password. There is no reset button on this device so I have no idea how you go about resetting the controller and APs. Hm it seems I can't create a new tag as a new user. If possible can someone add an "Aruba" tag?

  • ASP.Net validation controls

    - by nikolaosk
    In this post I would like to continue talking about validation in ASP.Net applications. I will look into the validation controls that ASP.Net provides. You can have a look at the first post in my blog regarding validation. You will show you that we can perform all our main validation tasks without almost writing any code. We will add validation to our form by adding one or more controls.We can also display messages to the user. The controls I am going to look into are: CompareValidator CustomValidator...(read more)

  • Error pages in ASP.NET

    - by koevoeter
    In ASP.NET you can retrieve the last unhandled exception via:(HttpContext.Current.)Server.GetLastError() // Server object is available as a property in Page and UserControl context This obviously only works in the same roundtrip. If you want to retrieve this information in your error page, you got a problem because the error page is not returned in the same roundtrip. The server responds with a redirect response and a new request to the error page is automatically sent. A common workaround would be to store the exception in your Session state from the Application_Error event in Global.asax. From ASP.NET 3.5 you can configure the redirect mode for error pages: <customErrors mode="On" defaultRedirect="~/Error.aspx" redirectMode="ResponseRewrite" /> This way the redirect response is not sent and the error page is returned right away. That implies that the browser is not aware of a page change and cannot reflect it in the address bar, so your original URL is not replaced with the URL of the error page, which might be what you actually want…

  • Running ASP.Net MVC3 Alongside ASP.Net WebForms in the Same Project

    - by Sam Abraham
    I previously blogged on running ASP.Net MVC in an ASP.Net WebForms project. My reference at the time was a freely-available PDF document by Scott Guthrie which covered the setup process in good detail.   As I am preparing references to share with our audience at my upcoming talk at the Deerfield Beach Coders Café on March 1st (http://www.fladotnet.com/Reg.aspx?EventID=514), I found a nice blog post by Scott Hanselman on running both ASP.Net 4.0 WebForms along with ASP.Net MVC 3.0 in the same project. You can access this article here.   Moreover, Scott later followed-up with a blog showing how to leverage NuGet to automate the setup of ASP.Net MVC3 in an existing ASP.Net WebForms project.   One frequent question that usually comes up when discussing this side-by-side setup is the loss of the convenient Visual Studio Solution Explorer context menu which enable us to easily create controllers and views with a few mouse clicks.   A good suggestion brought up in the comments section of Scott’s article presented a good work-around to this problem: Manually add the MVC Visual Studio Project Type GUID in your .sln solution file ({E53F8FEA-EAE0-44A6-8774-FFD645390401}) which then brings back the MVC-specific context menu functionality in solution explorer of the hybrid project.

  • Date Compare Validator Control ASP.NET

    - by Sahanr
    Compare two input dates to avoid invalid dates. In this example I have created two textboxes and namded as "TextBoxSeminarDate" and "TextBoxBookingDeadline". Booking deadline date must be before date to the Seminar date. Therefore I used Operator as "LesThanEqual". I have validated "TextBoxBookingDeadline" value comparing with the "TextBoxSeminarDate" value as follow.   <asp:CompareValidator ID="CompareValidatorBookingDeadline" runat="server" ControlToCompare="TextBoxSeminarDate" ControlToValidate="TextBoxBookingDeadline" Display="Dynamic" ErrorMessage="Please check the seminar date and select appropriate date for booking deadline" Operator="LessThanEqual" Type="Date"  ValueToCompare="<%= TextBoxSeminarDate.Text.ToShortString() %>">*</asp:CompareValidator> The important thing is "ValueToCompare" property of the compare validator. Here I have assined it to the value of the TextboxSeminarDate and then compered it with the booking deadline date.

  • Why after each restart, my local .NET sites take time to load for the first time?

    - by Saeed Neamati
    I'm developing sites based on .NET platform. I usually deploy these sites on my local IIS, so that I can test them and see their functionality before going live. However, each time I restart windows, it seems that sites take a long time to run for the first time. I know about JIT and I'm also aware of this question, but it doesn't answer my question. Does JIT happens every time you restart windows? Is it related to creation of w3wp.exe process? Why sites are so slow for the first request after each restart?

  • Windows 2008 Domain Controller - Backup (BDC) to Primary (PDC)

    - by Klaptrap
    I have created a new domain controller with my single domain forest. I have also made it DHCP and DNS ready - all 3 services have synchronised with the existing W2K8 domain controller. I even migrated the FSMO roles and thought everything was fine. Indeed all machines on network appear to obtain DHCP and DNS from new server and the AD is working on the new server as my internal website uses it for login authentication. I have just noticed, via BgInfo - Sys Internals - that the new server is showing as "backup" and the old as "primary" - I thought I had already achieved this. Have the FSMO roles swapped back - as I have yet to have removed the old server from AD (dcpromo). Do I need to do anything before I run dcpromo on the old server? Any thoughts appreciated....

  • How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment [closed]

    - by lmttag
    Possible Duplicate: How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment We have an ASP.NET Web API server that serves up a SQL Server data driven website. The API uses JSON to transfer data from SQL Server to the front end. We need to move it to an internal production environment (nothing will be exposed on the public Internet) and we’re having problems - or just not understanding what needs to be done. There are two domains: The corporate domain - where all users login normally. The process domain - contains the database the Web API needs to access. The IT staff wants to put a DMZ between the two domains to house the IIS app and shield the users on the corporate domain from having access into the process domain directly. The ideal configuration is: corp domain (end users) <–> firewall (open port 80) <–> DMZ (web server running IIS) <–> firewall (open port 80 or 1433????) <–> process domain (IIS for Web API and SQL Server) We don’t really understand how to deploy our browser/Web API application in this scenario. Do we need to break up our application so that all the client code is on the IIS server in the DMZ, while the Web API gets installed on the server in the process domain? Does the entire app (client code and Web API) stay together on the IIS server in the DMZ, which then somehow accesses the SQL Server instance to get data? From the IIS server and app in the DMZ, would you simply access the Web API on the server in the process domain by going to http://server/appname/api/getitmes? In the second firewall between the DMZ and the process domain, would you have to open port 1433 or just port 80 since the Web API is a HTTP endpoint? Or, is there some better way of deployment (i.e., how ASP.NET Web API single page applications written all in HTML5 and JavaScript supposed to be deployed to production environments?)? NB: The servers are Win2k8 R2, SQL Server 2k8 R2, and IIS 7.5.

  • Entity Framework 6: Alpha2 Now Available

    - by ScottGu
    The Entity Framework team recently announced the 2nd alpha release of EF6.   The alpha 2 package is available for download from NuGet. Since this is a pre-release package make sure to select “Include Prereleases” in the NuGet package manager, or execute the following from the package manager console to install it: PM> Install-Package EntityFramework -Pre This week’s alpha release includes a bunch of great improvements in the following areas: Async language support is now available for queries and updates when running on .NET 4.5. Custom conventions now provide the ability to override the default conventions that Code First uses for mapping types, properties, etc. to your database. Multi-tenant migrations allow the same database to be used by multiple contexts with full Code First Migrations support for independently evolving the model backing each context. Using Enumerable.Contains in a LINQ query is now handled much more efficiently by EF and the SQL Server provider resulting greatly improved performance. All features of EF6 (except async) are available on both .NET 4 and .NET 4.5. This includes support for enums and spatial types and the performance improvements that were previously only available when using .NET 4.5. Start-up time for many large models has been dramatically improved thanks to improved view generation performance. Below are some additional details about a few of the improvements above: Async Support .NET 4.5 introduced the Task-Based Asynchronous Pattern that uses the async and await keywords to help make writing asynchronous code easier. EF 6 now supports this pattern. This is great for ASP.NET applications as database calls made through EF can now be processed asynchronously – avoiding any blocking of worker threads. This can increase scalability on the server by allowing more requests to be processed while waiting for the database to respond. The following code shows an MVC controller that is querying a database for a list of location entities:     public class HomeController : Controller     {         LocationContext db = new LocationContext();           public async Task<ActionResult> Index()         {             var locations = await db.Locations.ToListAsync();               return View(locations);         }     } Notice above the call to the new ToListAsync method with the await keyword. When the web server reaches this code it initiates the database request, but rather than blocking while waiting for the results to come back, the thread that is processing the request returns to the thread pool, allowing ASP.NET to process another incoming request with the same thread. In other words, a thread is only consumed when there is actual processing work to do, allowing the web server to handle more concurrent requests with the same resources. A more detailed walkthrough covering async in EF is available with additional information and examples. Also a walkthrough is available showing how to use async in an ASP.NET MVC application. Custom Conventions When working with EF Code First, the default behavior is to map .NET classes to tables using a set of conventions baked into EF. For example, Code First will detect properties that end with “ID” and configure them automatically as primary keys. However, sometimes you cannot or do not want to follow those conventions and would rather provide your own. For example, maybe your primary key properties all end in “Key” instead of “Id”. Custom conventions allow the default conventions to be overridden or new conventions to be added so that Code First can map by convention using whatever rules make sense for your project. The following code demonstrates using custom conventions to set the precision of all decimals to 5. As with other Code First configuration, this code is placed in the OnModelCreating method which is overridden on your derived DbContext class:         protected override void OnModelCreating(DbModelBuilder modelBuilder)         {             modelBuilder.Properties<decimal>()                 .Configure(x => x.HasPrecision(5));           } But what if there are a couple of places where a decimal property should have a different precision? Just as with all the existing Code First conventions, this new convention can be overridden for a particular property simply by explicitly configuring that property using either the fluent API or a data annotation. A more detailed description of custom code first conventions is available here. Community Involvement I blogged a while ago about EF being released under an open source license.  Since then a number of community members have made contributions and these are included in EF6 alpha 2. Two examples of community contributions are: AlirezaHaghshenas contributed a change that increases the startup performance of EF for larger models by improving the performance of view generation. The change means that it is less often necessary to use of pre-generated views. UnaiZorrilla contributed the first community feature to EF: the ability to load all Code First configuration classes in an assembly with a single method call like the following: protected override void OnModelCreating(DbModelBuilder modelBuilder) {        modelBuilder.Configurations            .AddFromAssembly(typeof(LocationContext).Assembly); } This code will find and load all the classes that inherit from EntityTypeConfiguration<T> or ComplexTypeConfiguration<T> in the assembly where LocationContext is defined. This reduces the amount of coupling between the context and Code First configuration classes, and is also a very convenient shortcut for large models. Other upcoming features coming in EF 6 Lots of information about the development of EF6 can be found on the EF CodePlex site, including a roadmap showing the other features that are planned for EF6. One of of the nice upcoming features is connection resiliency, which will automate the process of retying database operations on transient failures common in cloud environments and with databases such as the Windows Azure SQL Database. Another often requested feature that will be included in EF6 is the ability to map stored procedures to query and update operations on entities when using Code First. Summary EF6 is the first open source release of Entity Framework being developed in CodePlex. The alpha 2 preview release of EF6 is now available on NuGet, and contains some really great features for you to try. The EF team are always looking for feedback from developers - especially on the new features such as custom Code First conventions and async support. To provide feedback you can post a comment on the EF6 alpha 2 announcement post, start a discussion or file a bug on the CodePlex site. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Implementing ASP.NET 4.0 Page.MetaDescription Property

    Before ASP.NET 4.0, you had to manually code your meta description tags. The meta description tag, though no longer used by major search engines in their ranking algorithm, is still an important factor for increasing website traffic. Bear in mind that searchers coming from search engines (such as Google) will only click on the results provided if the meta description is relevant to the query.
