httpmodule

问题 I have statiс files in website folder, but need to check permissions for every file. I decided to use HttpModule for that purposes. ASP.NET receives all the http-requests (I used wildcard mapping) and The algorith is the following: HttpModule receives the request HttpModule checks permissions If access is denied then the answer is "Forbidden". If all is OK then httpModule's method just returns. DefaultHttpHandler is automatically used to process request for static files The problem is that

问题 I am trying to design a system for something like this with ASP.net/C#. The users pay for downloading some content (files- mp3s/PDFs,doc etc).I should be able to track the number of bytes downloaded by the user. If the number of bytes downloaded match the number of bytes on the server, I should set a flag in DB (telling that the download was successful and prevent them from downloading the file again/asking them to pay for the download again). If the download was incomplete, they should be

问题 I've got the following IHttpModule and I'm trying to figure out how to execute an action from a controller for a given absolute or relative URL. public class CustomErrorHandlingModule : IHttpModule { #region Implementation of IHttpModule public void Init(HttpApplication context) { context.Error += (sender, e) => OnError(new HttpContextWrapper(((HttpApplication)sender).Context)); } public void Dispose() {} public void OnError(HttpContextBase context) { // Determine error resource to display,

问题 My question is simple (although the answer will most likely not be): I'm trying to decide how to implement a server side upload handler in C# / ASP.NET. I've used both HttpModules (IHttpModule interface) and HttpHandlers (IHttpHandler interface) and it occurs to me that I could implement this using either mechanism. It also occurs to me that I don't understand the differences between the two. So my question is this: In what cases would I choose to use IHttpHandler instead of IHttpModule (and

问题 I am developing a custom application feedback tool. The idea is that when the user launches a particular application, I want a pop-up to appear, say a couple seconds after the user launches the application, that asks if they'd be willing to provide feedback. The pop-up will simply be a new IE window. So, something similar in functionality to: Response.Write("<script>window.open('" + sUrl + "', 'mywindow','resizable= yes,scrollbars= yes');</script>"); We have numerous web apps (ASP.NET) in our

问题 I am attempting to do a redirect in the Application_Error handler in Global.asax. Nothing fancy at all. private void Application_Error(object sender, EventArgs e) { // ...snip... Server.Transfer(somePath, false); // ...snip... } This works great under Full trust, but I need to get it to work under Medium trust. The code I'm working on here needs to function properly in a shared hosting environment (Unfortunately, I have no control over this requirement). However, when I configure the site as

问题 I've read a post about httpHandlers and httpModules in ASP.NET and it said that there are such nodes (<httpModules> and <httpHandlers>) defined by default inside machine.config but when I looked they are not there. I've searched the machine.config at path "$WINDOWS$\Microsoft.NET\Framework\$VERSION$\CONFIG". The only references are these 2 lines: <section name="httpHandlers" type="System.Web.Configuration.HttpHandlersSection, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken

问题 An IHttpModule implementation I created public class ResponseTweaker : IHttpModule { // my module ... is registered in Web.config <system.web> <httpModules> <add name="redman" type="ResponseTweaker"/> </httpModules> and an instance of it is sitting in the pipeline. From the perspective of a caller (e.g. from the Global.asax.cs file), how should I get a reference to that module instance? 回答1: The modules can be found in HttpContext.Current.ApplicationInstance.Modules . You can look through the

问题 I am writing HttpModule and need to test it, I am using C# , .NET4.5.2 , NUnit and Moq . Method I am trying to test is Context_BeginRequest : public class XForwardedForRewriter : IHttpModule { public void Init(HttpApplication context) { context.BeginRequest += Context_BeginRequest; } public void Context_BeginRequest(object sender, EventArgs e) { ... } } sender here is HttpApplication and this is where the problems start,... one can create instance of HttpApplication however there is no way to

问题 I got a problem as i am writing a custom SSO solution for my company. To mkae it simple, i've made a custom authentication httpmodule that intercepts all requests so as to check user authentication state. If not authenticated, user is redirected to my custom sso login page. The thing is, when user is not authenticated, i'd like to check if he can access the requested page/resource... With Webforms, no problem, i add an authorization block in web.config, and i use UrlAuthorizationModule
