  • IHttpModule not being applied to virtual directory

    - by arthurdent510
    I have a network folder that is mapped to my iis app as a virtual directory and I'm trying to do some authentication for files that are located there with an ihttpmodule. I've verified that the ihttpmodule is firing properly for anything else in my app, just not the files located in virtual directory. Most of what I've found is that the directory can't be listed as an application (which it isn't), and everything should work. The other solution that I found was to add the the module tag to the tag, but that didn't seem to help either. Everything that I've found talks about stopping this from happening. So my question is what could be set that is causing this to not work? Is there a certain execute permission that needs to be set? Any other iis settings that could cause this? It is an mvc app, and this is how my directory structure is laid out: server/app <- my application folder server/app/content/downloads <- downloads is the virtual directory Do I have to add the virtual directory directly under my app directory? Is that part of the problem? I don't have direct control of the server my code is running on, so testing things out is a bit of a pain... so I was looking for some more thoughts before starting to send emails off to my operations people. Thanks!

  • Trouble determining proper decoding of a REST response from an ArcGIS REST service using IHttpModule

    - by Ryan Taylor
    First a little background on what I am trying to achieve. I have an application that is utilizing REST services served by ArcGIS Server and IIS7. The REST services return data in one of several different formats. I am requesting a JSON response. I want to be able to modify the response (remove or add parameters) before the response is sent to the client. However, I am having difficulty converting the stream to a string that I can modify. To that end, I have implemented the following code in order to try to inspect the stream. SecureModule.cs using System; using System.Web; namespace SecureModuleTest { public class SecureModule : IHttpModule { public void Init(HttpApplication context) { context.BeginRequest += new EventHandler(OnBeginRequest); } public void Dispose() { } public void OnBeginRequest(object sender, EventArgs e) { HttpApplication application = (HttpApplication) sender; HttpContext context = application.Context; HttpRequest request = context.Request; HttpResponse response = context.Response; response.Filter = new ServicesFilter(response.Filter); } } } ServicesFilter.cs using System; using System.IO; using System.Text; namespace SecureModuleTest { class ServicesFilter : MemoryStream { private readonly Stream _outputStream; private StringBuilder _content; public ServicesFilter(Stream output) { _outputStream = output; _content = new StringBuilder(); } public override void Write(byte[] buffer, int offset, int count) { _content.Append(Encoding.UTF8.GetString(buffer, offset, count)); using (TextWriter textWriter = new StreamWriter(@"C:\temp\content.txt", true)) { textWriter.WriteLine(String.Format("Buffer: {0}", _content.ToString())); textWriter.WriteLine(String.Format("Length: {0}", buffer.Length)); textWriter.WriteLine(String.Format("Offset: {0}", offset)); textWriter.WriteLine(String.Format("Count: {0}", count)); textWriter.WriteLine(""); textWriter.Close(); } // Modify response _outputStream.Write(buffer, offset, count); } } } The module is installed in the /ArcGIS/rest/ virtual directory and is executed via the following GET request. http://localhost/ArcGIS/rest/services/?f=json&pretty=true The web page displays the expected response, however, the text file tells a very different (encoded?) story. Expect Response {"currentVersion" : "10.0", "folders" : [], "services" : [ ] } Text File Contents Buffer: ? ?`I?%&/m?{J?J??t??`$?@??????iG#)?*??eVe]f@????{???{???;?N'????\fdl??J??!????~|?"~?G?u]???'?)??G?????G??7N????W??{?????,??|?OR????q?

  • Asp Dot Net : IHttpModule + m_context.Server.Transfer = session state error

    - by tinky05
    I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea?

  • Why can event handlers can only be bound to HttpApplication events during IHttpModule initialization

    - by Venemo
    This is just another "working in dev server, why not working in IIS" type question. So, I created a nice DAL using NHibernate as described here. When creating an ISession, I hook up an event handler to the HttpApplication.EndRequest to take care of cleaning it up. However, I deployed my site to IIS and it says: Event handlers can only be bound to HttpApplication events during IHttpModule initialization. Since when? What for? Why? How can I bypass it?

  • Move Global.asax to iHttpModule when using ASP.NET MVC

    - by rockinthesixstring
    I have successfully created an iHttpModule to replace my Global.asax file in many Web Forms applications. But in looking at the Global.asax file in my MVC application, the methods are totally different. I'm wondering if it is still possible to create this same thing in an MVC app. I know it's not necessary and the Global.asax works just fine. I suppose I just want to have nothing but the web.config in the root directory of my application. Also, I am putting all of my classes in a separate class library project instead of a folder in my MVC application. Not sure if this makes a difference or not.

  • How to add custom Authentication Type in IIS7(.5)

    - by user312769
    I am busy developing a IHttpModule, which will do our custom authentication using our own credential store. I would like to know how to add a new custom Authentication Type to the list (Anonymous, Basic, Forms etc.) in InetMgr under Authentication and how I would know which Authenticaiton Type has been enabled in the IHttpModule class.

  • Request-local storage in ASP.NET (accessible to the code from IHttpModule implementation)

    - by IgorK
    I need to have some object hanging around between two events I'm interested in: PreRequestHandlerExecute (where I create an instance of my object and want to save it) and PostRequestHandlerExecute (where I want to get to the object). After the second event the object is not needed for my purposes and should be discarded either by storage or my explicit action. So the ideal context where my object should be stored is per request (with guaranteed no sharing issues when different threads are serving requests... or processes/servers :) ) Take into account that actual implementation I can do is being made from a HttpModule and is supposed to be a pluggable solution for already written web apps (so the option to provide some state using static/instance variables in Global.asax doesn't look good - I will have to modify Global.asax on every web application). Cache seems to be too broad for this use. I tried to see whether httpContext.Application (of type HttpApplicationState) is good for me or not, but cannot get whether it is exactly per HttpApplication instance or not (AFAIK you can have several instances of HttpApplications used on different threads and therefore serving several requests simultaneously - then using storage shared between threads will not work correctly; otherwise I would use it because one HttpApplication instance serves exactly one request at a time). Something could be done with storing state on the HttpModule instances if I know for sure that it's exactly bound 1-to-1 with every HttpApplication instance running (but again I need a proof that HttpApplication instance is 1-to-1 with my HttpModule's instance). Any valuable and reputable links on these topics are much appreciated... Would be great to find something particularly well-suited for per request situation (because otherwise I may end up with something ulgy... probably either some 'broader' scoped storage and some hacks to have different keys in the storage for different requests, OR using a thread-local thing and in this way commit to the theory that IIS/ASP.NET will not ever serve first event from one thread and the second event from the other thread and so on)

  • Custom authentication module inheriting IHttpModule issue.

    - by Chandan Khatwani
    LoginPage.aspx:- protected void Button1_Click(object sender, EventArgs e) { Context.Items["Username"] = txtUserId.Text; Context.Items["Password"] = txtPassword.Text; // FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, Context.Items["Username"].ToString(), DateTime.Now, DateTime.Now.AddMinutes(10), true, "users", FormsAuthentication.FormsCookiePath); // Encrypt the cookie using the machine key for secure transport string hash = FormsAuthentication.Encrypt(ticket); HttpCookie cookie = new HttpCookie( FormsAuthentication.FormsCookieName, // Name of auth cookie hash); // Hashed ticket // Set the cookie's expiration time to the tickets expiration time if (ticket.IsPersistent) cookie.Expires = ticket.Expiration; Response.Cookies.Add(cookie); Response.Redirect("Default.aspx"); } Global.asax file:- void Application_AuthenticateRequest(object sender, EventArgs e) { if (HttpContext.Current.User != null) { if (HttpContext.Current.User.Identity.IsAuthenticated) { if (HttpContext.Current.User.Identity is FormsIdentity) { FormsIdentity id = (FormsIdentity)HttpContext.Current.User.Identity; FormsAuthenticationTicket ticket = id.Ticket; // Get the stored user-data, in this case, our roles string userData = ticket.UserData; string[] roles = userData.Split(','); HttpContext.Current.User = new System.Security.Principal.GenericPrincipal(id, roles); Response.Write(HttpContext.Current.User.Identity.Name); Response.Redirect("Default.aspx"); } } } } I get the following error after signing in This webpage has a redirect loop. The webpage at http://localhost:1067/Default.aspx has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

  • Frame Redirect in C#

    - by Simon Linder
    I would like to execute a frame redirect in C# from my managed module for the IIS 7. When I call context.Response.Redirect(@"http://www.myRedirect.org");the correct page is shown but also the address is shown in the browser. And that is exactly what I do not want. So I want something like: private void OnBeginRequest(object sender, EventArgs e) { HttpApplication app = (HttpApplication)sender; HttpContext context = app.Context; // make a frame redirect if a specified page is called if (context.Request.ServerVariable["HTTP_REFERER"].Equals(@"http://www.myPage.org/1.html")) { // perform the frame redirect here, but how? // so something like context.Response.Redirect(@"http://www.myRedirect.org"); // but as I said that doesn't redirect as I want it to be } } Any ideas about that?

  • Logging raw HTTP request/response in ASP.NET MVC & IIS7

    - by Greg Beech
    I'm writing a web service (using ASP.NET MVC) and for support purposes we'd like to be able to log the requests and response in as close as possible to the raw, on-the-wire format (i.e including HTTP method, path, all headers, and the body) into a database. What I'm not sure of is how to get hold of this data in the least 'mangled' way. I can re-constitute what I believe the request looks like by inspecting all the properties of the HttpRequest object and building a string from them (and similarly for the response) but I'd really like to get hold of the actual request/response data that's sent on the wire. I'm happy to use any interception mechanism such as filters, modules, etc. and the solution can be specific to IIS7. However, I'd prefer to keep it in managed code only. Any recommendations? Edit: I note that HttpRequest has a SaveAs method which can save the request to disk but this reconstructs the request from the internal state using a load of internal helper methods that cannot be accessed publicly (quite why this doesn't allow saving to a user-provided stream I don't know). So it's starting to look like I'll have to do my best to reconstruct the request/response text from the objects... groan. Edit 2: Please note that I said the whole request including method, path, headers etc. The current responses only look at the body streams which does not include this information. Edit 3: Does nobody read questions around here? Five answers so far and yet not one even hints at a way to get the whole raw on-the-wire request. Yes, I know I can capture the output streams and the headers and the URL and all that stuff from the request object. I already said that in the question, see: I can re-constitute what I believe the request looks like by inspecting all the properties of the HttpRequest object and building a string from them (and similarly for the response) but I'd really like to get hold of the actual request/response data that's sent on the wire. If you know the complete raw data (including headers, url, http method, etc.) simply cannot be retrieved then that would be useful to know. Similarly if you know how to get it all in the raw format (yes, I still mean including headers, url, http method, etc.) without having to reconstruct it, which is what I asked, then that would be very useful. But telling me that I can reconstruct it from the HttpRequest/HttpResponse objects is not useful. I know that. I already said it. Please note: Before anybody starts saying this is a bad idea, or will limit scalability, etc., we'll also be implementing throttling, sequential delivery, and anti-replay mechanisms in a distributed environment, so database logging is required anyway. I'm not looking for a discussion of whether this is a good idea, I'm looking for how it can be done.

  • How to manipulate a header and then continue with it in C#?

    - by Simon Linder
    Hi all, I want to replace an old ISAPI filter that ran on IIS6. This filter checks if the request is of a special kind, then manipulates the header and continues with the request. Two headers are added in the manipulating method that I need for calling another special ISAPI module. So I have ISAPI C++ code like: DWORD OnPreProc(HTTP_FILTER_CONTEXT *pfc, HTTP_FILTER_PREPROC_HEADERS *pHeaders) { if (ManipulateHeaderInSomeWay(pfc, pHeaders)) { return SF_STATUS_REQ_NEXT_NOTIFICATION; } return SF_STATUS_REQ_FINISHED; } I now want to rewrite this ISAPI filter as a managed module for the IIS7. So I have something like this: private void OnMapRequestHandler(HttpContext context) { ManipulateHeaderInSomeWay(context); } And now what? The request seems not to do what it should? I already wrote an IIS7 native module that implements the same method. But this method has a return value with which I can tell what to do next: REQUEST_NOTIFICATION_STATUS CMyModule::OnMapRequestHandler(IN IHttpContext *pHttpContext, OUT IMapHandlerProvider *pProvider) { if (DoSomething(pHttpContext)) { return RQ_NOTIFICATION_CONTINUE; } return RQ_NOTIFICATION_FINISH_REQUEST; } So is there a way to send my manipulated context again?

  • Adding an Admin user to an ASP.NET MVC 4 application using a single drop-in file

    - by Jon Galloway
    I'm working on an ASP.NET MVC 4 tutorial and wanted to set it up so just dropping a file in App_Start would create a user named "Owner" and assign them to the "Administrator" role (more explanation at the end if you're interested). There are reasons why this wouldn't fit into most application scenarios: It's not efficient, as it checks for (and creates, if necessary) the user every time the app starts up The username, password, and role name are hardcoded in the app (although they could be pulled from config) Automatically creating an administrative account in code (without user interaction) could lead to obvious security issues if the user isn't informed However, with some modifications it might be more broadly useful - e.g. creating a test user with limited privileges, ensuring a required account isn't accidentally deleted, or - as in my case - setting up an account for demonstration or tutorial purposes. Challenge #1: Running on startup without requiring the user to install or configure anything I wanted to see if this could be done just by having the user drop a file into the App_Start folder and go. No copying code into Global.asax.cs, no installing addition NuGet packages, etc. That may not be the best approach - perhaps a NuGet package with a dependency on WebActivator would be better - but I wanted to see if this was possible and see if it offered the best experience. Fortunately ASP.NET 4 and later provide a PreApplicationStartMethod attribute which allows you to register a method which will run when the application starts up. You drop this attribute in your application and give it two parameters: a method name and the type that contains it. I created a static class named PreApplicationTasks with a static method named, then dropped this attribute in it: [assembly: PreApplicationStartMethod(typeof(PreApplicationTasks), "Initializer")] That's it. One small gotcha: the namespace can be a problem with assembly attributes. I decided my class didn't need a namespace. Challenge #2: Only one PreApplicationStartMethod per assembly In .NET 4, the PreApplicationStartMethod is marked as AllMultiple=false, so you can only have one PreApplicationStartMethod per assembly. This was fixed in .NET 4.5, as noted by Jon Skeet, so you can have as many PreApplicationStartMethods as you want (allowing you to keep your users waiting for the application to start indefinitely!). The WebActivator NuGet package solves the multiple instance problem if you're in .NET 4 - it registers as a PreApplicationStartMethod, then calls any methods you've indicated using [assembly: WebActivator.PreApplicationStartMethod(type, method)]. David Ebbo blogged about that here:  Light up your NuGets with startup code and WebActivator. In my scenario (bootstrapping a beginner level tutorial) I decided not to worry about this and stick with PreApplicationStartMethod. Challenge #3: PreApplicationStartMethod kicks in before configuration has been read This is by design, as Phil explains. It allows you to make changes that need to happen very early in the pipeline, well before Application_Start. That's fine in some cases, but it caused me problems when trying to add users, since the Membership Provider configuration hadn't yet been read - I got an exception stating that "Default Membership Provider could not be found." The solution here is to run code that requires configuration in a PostApplicationStart method. But how to do that? Challenge #4: Getting PostApplicationStartMethod without requiring WebActivator The WebActivator NuGet package, among other things, provides a PostApplicationStartMethod attribute. That's generally how I'd recommend running code that needs to happen after Application_Start: [assembly: WebActivator.PostApplicationStartMethod(typeof(TestLibrary.MyStartupCode), "CallMeAfterAppStart")] This works well, but I wanted to see if this would be possible without WebActivator. Hmm. Well, wait a minute - WebActivator works in .NET 4, so clearly it's registering and calling PostApplicationStartup tasks somehow. Off to the source code! Sure enough, there's even a handy comment in ActivationManager.cs which shows where PostApplicationStartup tasks are being registered: public static void Run() { if (!_hasInited) { RunPreStartMethods(); // Register our module to handle any Post Start methods. But outside of ASP.NET, just run them now if (HostingEnvironment.IsHosted) { Microsoft.Web.Infrastructure.DynamicModuleHelper.DynamicModuleUtility.RegisterModule(typeof(StartMethodCallingModule)); } else { RunPostStartMethods(); } _hasInited = true; } } Excellent. Hey, that DynamicModuleUtility seems familiar... Sure enough, K. Scott Allen mentioned it on his blog last year. This is really slick - a PreApplicationStartMethod can register a new HttpModule in code. Modules are run right after application startup, so that's a perfect time to do any startup stuff that requires configuration to be read. As K. Scott says, it's this easy: using System; using System.Web; using Microsoft.Web.Infrastructure.DynamicModuleHelper; [assembly:PreApplicationStartMethod(typeof(MyAppStart), "Start")] public class CoolModule : IHttpModule { // implementation not important // imagine something cool here } public static class MyAppStart { public static void Start() { DynamicModuleUtility.RegisterModule(typeof(CoolModule)); } } Challenge #5: Cooperating with SimpleMembership The ASP.NET MVC Internet template includes SimpleMembership. SimpleMembership is a big improvement over traditional ASP.NET Membership. For one thing, rather than forcing a database schema, it can work with your database schema. In the MVC 4 Internet template case, it uses Entity Framework Code First to define the user model. SimpleMembership bootstrap includes a call to InitializeDatabaseConnection, and I want to play nice with that. There's a new [InitializeSimpleMembership] attribute on the AccountController, which calls \Filters\InitializeSimpleMembershipAttribute.cs::OnActionExecuting(). That comment in that method that says "Ensure ASP.NET Simple Membership is initialized only once per app start" which sounds like good advice. I figured the best thing would be to call that directly: new Mvc4SampleApplication.Filters.InitializeSimpleMembershipAttribute().OnActionExecuting(null); I'm not 100% happy with this - in fact, it's my least favorite part of this solution. There are two problems - first, directly calling a method on a filter, while legal, seems odd. Worse, though, the Filter lives in the application's namespace, which means that this code no longer works well as a generic drop-in. The simplest workaround would be to duplicate the relevant SimpleMembership initialization code into my startup code, but I'd rather not. I'm interested in your suggestions here. Challenge #6: Module Init methods are called more than once When debugging, I noticed (and remembered) that the Init method may be called more than once per page request - it's run once per instance in the app pool, and an individual page request can cause multiple resource requests to the server. While SimpleMembership does have internal checks to prevent duplicate user or role entries, I'd rather not cause or handle those exceptions. So here's the standard single-use lock in the Module's init method: void IHttpModule.Init(HttpApplication context) { lock (lockObject) { if (!initialized) { //Do stuff } initialized = true; } } Putting it all together With all of that out of the way, here's the code I came up with: using Mvc4SampleApplication.Filters; using System.Web; using System.Web.Security; using WebMatrix.WebData; [assembly: PreApplicationStartMethod(typeof(PreApplicationTasks), "Initializer")] public static class PreApplicationTasks { public static void Initializer() { Microsoft.Web.Infrastructure.DynamicModuleHelper.DynamicModuleUtility .RegisterModule(typeof(UserInitializationModule)); } } public class UserInitializationModule : IHttpModule { private static bool initialized; private static object lockObject = new object(); private const string _username = "Owner"; private const string _password = "p@ssword123"; private const string _role = "Administrator"; void IHttpModule.Init(HttpApplication context) { lock (lockObject) { if (!initialized) { new InitializeSimpleMembershipAttribute().OnActionExecuting(null); if (!WebSecurity.UserExists(_username)) WebSecurity.CreateUserAndAccount(_username, _password); if (!Roles.RoleExists(_role)) Roles.CreateRole(_role); if (!Roles.IsUserInRole(_username, _role)) Roles.AddUserToRole(_username, _role); } initialized = true; } } void IHttpModule.Dispose() { } } The Verdict: Is this a good thing? Maybe. I think you'll agree that the journey was undoubtedly worthwhile, as it took us through some of the finer points of hooking into application startup, integrating with membership, and understanding why the WebActivator NuGet package is so useful Will I use this in the tutorial? I'm leaning towards no - I think a NuGet package with a dependency on WebActivator might work better: It's a little more clear what's going on Installing a NuGet package might be a little less error prone than copying a file A novice user could uninstall the package when complete It's a good introduction to NuGet, which is a good thing for beginners to see This code either requires either duplicating a little code from that filter or modifying the file to use the namespace Honestly I'm undecided at this point, but I'm glad that I can weigh the options. If you're interested: Why are you doing this? I'm updating the MVC Music Store tutorial to ASP.NET MVC 4, taking advantage of a lot of new ASP.NET MVC 4 features and trying to simplify areas that are giving people trouble. One change that addresses both needs us using the new OAuth support for membership as much as possible - it's a great new feature from an application perspective, and we get a fair amount of beginners struggling with setting up membership on a variety of database and development setups, which is a distraction from the focus of the tutorial - learning ASP.NET MVC. Side note: Thanks to some great help from Rick Anderson, we had a draft of the tutorial that was looking pretty good earlier this summer, but there were enough changes in ASP.NET MVC 4 all the way up to RTM that there's still some work to be done. It's high priority and should be out very soon. The one issue I ran into with OAuth is that we still need an Administrative user who can edit the store's inventory. I thought about a number of solutions for that - making the first user to register the admin, or the first user to use the username "Administrator" is assigned to the Administrator role - but they both ended up requiring extra code; also, I worried that people would use that code without understanding it or thinking about whether it was a good fit.

  • HTTP Module in detail

    - by Jalpesh P. Vadgama
    I know this post may sound like very beginner level. But I have already posted two topics regarding HTTP Handler and HTTP module and this will explain how http module works in the system. I have already posted What is the difference between HttpModule and HTTPHandler here. Same way I have posted about an HTTP Handler example here as people are still confused with it. In this post I am going to explain about HTTP Module in detail. What is HTTP Module As we all know that when ASP.NET Runtimes receives any request it will execute a series of HTTP Pipeline extensible objects. HTTP Module and HTTP handler play important role in extending this HTTP Pipelines. HTTP Module are classes that will pre and post process request as they pass into HTTP Pipelines.  So It’s one kind of filter we can say which will do some procession on begin request and end request. If we have to create HTTP Module we have to implement System.Web.IHttpModule interface in our custom class. An IHTTP Module contains two method dispose where you can write your clean up code and another is Init where your can write your custom code to handle request. Here you can your event handler that will execute at the time of begin request and end request. Let’s create an HTTP Module which will just print text in browser with every request. Here is the code for that. using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace Experiment { public class MyHttpModule:IHttpModule { public void Dispose() { //add clean up code here if required } public void Init(HttpApplication context) { context.BeginRequest+=new EventHandler(context_BeginRequest); context.EndRequest+=new EventHandler(context_EndRequest); } public void context_BeginRequest(object o, EventArgs args) { HttpApplication app = (HttpApplication)o; if (app != null) { app.Response.Write("<h1>Begin Request Executed</h1>"); } } public void context_EndRequest(object o, EventArgs args) { HttpApplication app = (HttpApplication)o; if (app != null) { app.Response.Write("<h1>End Request Executed</h1>"); } } } } Here in above code you can see that I have created two event handler context_Beginrequest and context_EndRequest which will execute at begin request and end request when request are processed. In this event handler I have just written a code to print text on browser. Now In order enable this HTTP Module in HTTP pipeline we have to put a settings in web.config  HTTPModules section to tell which HTTPModule is enabled. Below is code for HTTPModule. <configuration> <system.web> <compilation debug="true" targetFramework="4.0" /> <httpModules> <add name="MyHttpModule" type="Experiment.MyHttpModule,Experiment"/> </httpModules> </system.web> </configuration> Now I just have created a sample webform with following code in HTML like following. <form id="form1" runat="server"> <B>test of HTTP Module</B> </form> Now let’s run this web form in browser and you can see here it the output as expected.   Technorati Tags: HTTPModule,ASP.NET,Request

  • HttpModule with ASP.NET MVC not being called

    I am trying to implement a session-per-request pattern in an ASP.NET MVC 2 Preview 1 application, and I've implemented an IHttpModule to help me do this: public class SessionModule : IHttpModule { public void Init(HttpApplication context) { context.Response.Write("Init!"); context.EndRequest += context_EndRequest; } // ... etc... } And I've put this into the web.config: <system.web> <httpModules> <add name="SessionModule" type="MyNamespace.SessionModule" /> </httpModules> <system.webServer> <modules runAllManagedModulesForAllRequests="true"> <remove name="SessionModule" /> <add name="SessionModule" type="MyNamespace.SessionModule" /> </modules> However, "Init!" never gets written to the page (I'm using the built-in VS web server, Cassini). Additionally, I've tried putting breakpoints in the SessionModule but they never break. What am I missing?

  • Please help! request compression

    - by Naor
    Hi, I wrote an IHttpModule that compress my respone using gzip (I return a lot of data) in order to reduce response size. It is working great as long as the web service doesn't throws an exception. In case exception is thrown, the exception gzipped but the Content-encoding header is disappear and the client doesn't know to read the exception. How can I solve this? Why the header is missing? I need to get the exception in the client. Here is the module: public class JsonCompressionModule : IHttpModule { public JsonCompressionModule() { } public void Dispose() { } public void Init(HttpApplication app) { app.BeginRequest += new EventHandler(Compress); } private void Compress(object sender, EventArgs e) { HttpApplication app = (HttpApplication)sender; HttpRequest request = app.Request; HttpResponse response = app.Response; try { //Ajax Web Service request is always starts with application/json if (request.ContentType.ToLower(CultureInfo.InvariantCulture).StartsWith("application/json")) { //User may be using an older version of IE which does not support compression, so skip those if (!((request.Browser.IsBrowser("IE")) && (request.Browser.MajorVersion <= 6))) { string acceptEncoding = request.Headers["Accept-Encoding"]; if (!string.IsNullOrEmpty(acceptEncoding)) { acceptEncoding = acceptEncoding.ToLower(CultureInfo.InvariantCulture); if (acceptEncoding.Contains("gzip")) { response.AddHeader("Content-encoding", "gzip"); response.Filter = new GZipStream(response.Filter, CompressionMode.Compress); } else if (acceptEncoding.Contains("deflate")) { response.AddHeader("Content-encoding", "deflate"); response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress); } } } } } catch (Exception ex) { int i = 4; } } } Here is the web service: [WebMethod] public void DoSomething() { throw new Exception("This message get currupted on the client because the client doesn't know it gzipped."); } I appriciate any help. Thanks!

  • httpHandler - subfolder issue

    - by Patto
    Hi, I am trying to redirect my old typepad blog to my new blog (permanent 301 redirect) that runs with wordpress. The new blog will also be on a new server. the old Blog had the following structure: http://subdomain.domain.com/weblog/year/month/what-ever-article.html The new Blog looks like this: http://www.domain.com/Blog/year/month/what-ever-article.html I am using an http handler that I found online and tried to work with it: public class MyHttpModule :IHttpModule { public MyHttpModule() { // // TODO: Add constructor logic here // } #region IHttpModule Members public void Dispose() { } public void Init(HttpApplication context) { context.BeginRequest += new EventHandler(context_BeginRequest); } void context_BeginRequest(object sender, EventArgs e) { string oldURL = System.Web.HttpContext.Current.Request.Url.ToString(); string newURL = String.Empty; //oldURL = if (oldURL.ToString().ToLower().IndexOf("articles") >= 0 || System.Web.HttpContext.Current.Request.Url.ToString().ToLower().IndexOf("weblog") >= 0) { newURL = oldURL.Replace("subdomain.domain.com/weblog", "www.domain.com/Blog/index.php"); if (newURL.ToLower().Contains("subdomain")) { newURL = "http://www.domain.com/Blog"; } } else { newURL = "http://www.domain.com/Blog"; } System.Web.HttpContext.Current.Response.Clear(); System.Web.HttpContext.Current.Response.StatusCode = 301; System.Web.HttpContext.Current.Response.AddHeader("Location", newURL); System.Web.HttpContext.Current.Response.End(); } #endregion } To use this code, I put the handler into the web.config <httpModules> <add name="MyHttpModule" type="MyHttpModule, App_Code"/> </httpModules> The issue that I have is that when I want to redirect from the http://subdomain.domain.com/weblog/year/month/what-ever-article.html, I get an error that the folder would not exist. Is there any way to change my script or add an catch all to the web.config that forwards the URL to my script? When I use "http://subdomain.domain.com/weblog/year/month/what-ever-article.html" in oldURL string, then the redirect works just fine... so I must have some IIS or web.config settings wrong. Thanks in advance, Patrick

  • Change English numbers to Persian and vice versa in MVC (httpmodule)?

    - by Mohammad
    I wanna change all English numbers to Persian for showing to users. and change them to English numbers again for giving all requests (Postbacks) e.g: we have something like this in view IRQ170, I wanna show IRQ??? to users and give IRQ170 from users. I know, I have to use Httpmodule, But I don't know how ? Could you please guide me? Edit : Let me describe more : I've written the following http module : using System; using System.Collections.Specialized; using System.Diagnostics; using System.IO; using System.Text; using System.Text.RegularExpressions; using System.Web; using System.Web.UI; using Smartiz.Common; namespace Smartiz.UI.Classes { public class PersianNumberModule : IHttpModule { private StreamWatcher _watcher; #region Implementation of IHttpModule /// <summary> /// Initializes a module and prepares it to handle requests. /// </summary> /// <param name="context">An <see cref="T:System.Web.HttpApplication"/> that provides access to the methods, properties, and events common to all application objects within an ASP.NET application </param> public void Init(HttpApplication context) { context.BeginRequest += ContextBeginRequest; context.EndRequest += ContextEndRequest; } /// <summary> /// Disposes of the resources (other than memory) used by the module that implements <see cref="T:System.Web.IHttpModule"/>. /// </summary> public void Dispose() { } #endregion private void ContextBeginRequest(object sender, EventArgs e) { HttpApplication context = sender as HttpApplication; if (context == null) return; _watcher = new StreamWatcher(context.Response.Filter); context.Response.Filter = _watcher; } private void ContextEndRequest(object sender, EventArgs e) { HttpApplication context = sender as HttpApplication; if (context == null) return; _watcher = new StreamWatcher(context.Response.Filter); context.Response.Filter = _watcher; } } public class StreamWatcher : Stream { private readonly Stream _stream; private readonly MemoryStream _memoryStream = new MemoryStream(); public StreamWatcher(Stream stream) { _stream = stream; } public override void Flush() { _stream.Flush(); } public override int Read(byte[] buffer, int offset, int count) { int bytesRead = _stream.Read(buffer, offset, count); string orgContent = Encoding.UTF8.GetString(buffer, offset, bytesRead); string newContent = orgContent.ToEnglishNumber(); int newByteCountLength = Encoding.UTF8.GetByteCount(newContent); Encoding.UTF8.GetBytes(newContent, 0, Encoding.UTF8.GetByteCount(newContent), buffer, 0); return newByteCountLength; } public override void Write(byte[] buffer, int offset, int count) { string strBuffer = Encoding.UTF8.GetString(buffer, offset, count); MatchCollection htmlAttributes = Regex.Matches(strBuffer, @"(\S+)=[""']?((?:.(?![""']?\s+(?:\S+)=|[>""']))+.)[""']?", RegexOptions.IgnoreCase | RegexOptions.Multiline); foreach (Match match in htmlAttributes) { strBuffer = strBuffer.Replace(match.Value, match.Value.ToEnglishNumber()); } MatchCollection scripts = Regex.Matches(strBuffer, "<script[^>]*>(.*?)</script>", RegexOptions.Singleline | RegexOptions.IgnoreCase | RegexOptions.Multiline | RegexOptions.IgnorePatternWhitespace); foreach (Match match in scripts) { MatchCollection values = Regex.Matches(match.Value, @"([""'])(?:(?=(\\?))\2.)*?\1", RegexOptions.Singleline | RegexOptions.IgnoreCase | RegexOptions.Multiline | RegexOptions.IgnorePatternWhitespace); foreach (Match stringValue in values) { strBuffer = strBuffer.Replace(stringValue.Value, stringValue.Value.ToEnglishNumber()); } } MatchCollection styles = Regex.Matches(strBuffer, "<style[^>]*>(.*?)</style>", RegexOptions.Singleline | RegexOptions.IgnoreCase | RegexOptions.Multiline | RegexOptions.IgnorePatternWhitespace); foreach (Match match in styles) { strBuffer = strBuffer.Replace(match.Value, match.Value.ToEnglishNumber()); } byte[] data = Encoding.UTF8.GetBytes(strBuffer); _memoryStream.Write(data, offset, count); _stream.Write(data, offset, count); } public override string ToString() { return Encoding.UTF8.GetString(_memoryStream.ToArray()); } #region Rest of the overrides public override bool CanRead { get { throw new NotImplementedException(); } } public override bool CanSeek { get { throw new NotImplementedException(); } } public override bool CanWrite { get { throw new NotImplementedException(); } } public override long Seek(long offset, SeekOrigin origin) { throw new NotImplementedException(); } public override void SetLength(long value) { throw new NotImplementedException(); } public override long Length { get { throw new NotImplementedException(); } } public override long Position { get { throw new NotImplementedException(); } set { throw new NotImplementedException(); } } #endregion } } It works well, but It converts all numbers in css and scripts files to Persian and it causes error.

  • Custom MembershipProvider attempts to pass empty creds after IIS restart

    - by Joseph DeCarlo
    I have a C# custom ASP.Net MembershipProvider. When the user attempts to navigate to another part of the site after IIS is restarted, it doesn't navigate to the login page to collect credentials, but instead attempts to authenticate with empty credentials. Can anyone tell me what I have to do to identify that the new authentication needs to take place and that new creds need to be gathered? I have a complementary custom IHttpModule implementation that allows me to intercept events like BeginRequest and AuthenticateRequest, if that helps.

  • .Net WebDAV Server

    - by Andrew Theken
    Hi all, I am looking to implement a WebDAV server in ASP.Net. the app will be deployed to IIS 6. I have seen a few frameworks that provide this functionality, but I can't seem to identify how they're able to accomplish it without (apparently) modifying IIS settings. My specific question is how do I configure IIS and ASP.Net so that a IHttpModule/IHttpHandler might have an opportunity to handle any of the additional WebDAV verbs (i.e. LOCK, OPTIONS, PROFIND, etc.)

  • HttpHandler instance and HttpApplication object - does the latter...?

    - by SourceC
    A Book showed an example where ( when using IIS7 ) the following module was configured such that it would be used by any web application ( even by non-asp.net apps ) running on a web site. But: A) if this module is invoked for non-asp.net application, then how or why would HttpApplication object still be created, since non-asp.net apps don’t run in the context of CLR ( and thus Asp.Net runtime also won’t run )? b) Assuming HttpApplication object is also created for non-asp.net apps, why then does the code inside Init() event handler have to check for whether HttpApplication object actually exists? Why wouldn’t it exist? Isn’t this HttpApplication object which actually instantiates Http module instance? Here is Http handler: public class SimpleSqlLogging : IHttpModule { private HttpApplication _CurrentApplication; public void Dispose() { _CurrentApplication = null; } public void Init(HttpApplication context) { // Attach to the incoming request event _CurrentApplication = context; if (context != null) { context.BeginRequest += new EventHandler(context_BeginRequest); } } void context_BeginRequest(object sender, EventArgs e) { ... } }

  • How to dispose NHibernate ISession in an ASP.NET MVC App

    - by Joe Young
    I have NHibernate hooked up in my asp.net mvc app. Everything works fine, if I DON'T dispose the ISession. I have read however that you should dispose, but when I do, I get random "Session is closed" exceptions. I am injecting the ISession into my other objects with Windsor. Here is my current NHModule: public class NHibernateHttpModule : IHttpModule { public void Init(HttpApplication context) { context.BeginRequest += context_BeginRequest; context.EndRequest += context_EndRequest; } static void context_EndRequest(object sender, EventArgs e) { CurrentSessionContext.Unbind(MvcApplication.SessionFactory); } static void context_BeginRequest(object sender, EventArgs e) { CurrentSessionContext.Bind(MvcApplication.SessionFactory.OpenSession()); } public void Dispose() { // do nothing } } Registering the ISession: container .Register(Component.For<ISession>() .UsingFactoryMethod(() => MvcApplication.SessionFactory.GetCurrentSession()).LifeStyle.Transient); The error happens when I tack the Dispose on the unbind in the module. Since I keep getting the session is closed error I assume this is not the correct way to do this, so what is the correct way? Thanks, Joe
