Asp.net -an HttpModule To Perform Extension-Less URL Rewriting With IIS7"?
Nov 9, 2010
I've implemented "Approach 3: Using an HttpModule to Perform Extension-Less URL Rewriting with IIS7" from here:http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx That is based on URLRewriter module:http://urlrewriter.net/.It seems to work on my local environment but on production server (running IIS 7) it shows "404 - File or directory not found" page.I've searched on Google and could not seem to find the solution.In the end,we went back to IIS 6 and followed the instructions here which worked:http://urlrewriter.net/index.php/support/installation/windows-server-2003.But someday we may have to upgrade to IIS 7 on a shared hosting environment and the same issue will appear again!
I am working on url rewriting all is working fine on my local machine when i upload this site on production server the link of url rewrite which is extension less not work. i search the multiple solution in the google one solution is that insert the aspnet_isapi.dll in the properties->virtual directory tab->configuration->insert aspnet_isapi.dll site in working, but problem is that hosting provider refuse to add this dll. tell me alternate solution to add this dll from web.config file.
In IIS6 the scenario below is working perfectly.I have an HttpModule called URLRedirect which examines URLS and by using RegEx rewrites of applicable. An example is a URL "/doc47.pdf" gets redirected to docpdf.ashx?id=47 Then the docpdf.ashx used the id value and, using a database builds an application/pdf document and returns it. Since I need to validate that the user has access to the data, the first line of the ProcessRequest(HttpContext context) function is:if (context.User.Identity.IsAuthenticated) ..... This is where the problem occurs, but more details first.
On a webpage, access to which is restricted to lgged on users who meet certain criteria there is a link which allows the user to present the page as a PDF document. This is achieved by using javascript to open a popup window using the window.open("/doc47.pdf", ... ) function.This all works fine under IIS6 and under IIS7 if I change the mode to Classic. But, under IIS7 in integrated mode, the following happens.The line in doc.ashx described above raises an exception because context.User == null. But, and this is interesting, if instead of using the link that opens the popup window I instead type /doc.pdf?id=47 into the address bar, the PDF document displays correctly.So this indicates to me that the URLRedirect Module is somehow losing the logged on user information.
I'm using Intelligencia url rewriting currently but have just leased an IIS 7.5 server to put my asp.net 3.5 site on. I installed the IIS URL rewriting module and was amazed at how easy it was to create rules. Creating rules with the Intelligencia url rewriter is complicated (at least for me). Are there any downsides to switching? Is there a reason for me not to move on to the Microsoft solution? This site isn't live yet, so I have time to switch
am trying to write an HttpModule that will work in IIS7 with integrated pipeline mode AppPool. Within this module I need to access Session variables and to be able to capture the Session Start and End events. I have found a couple of articles on this topic that indicate the need to modify the behavior of the HttpHandler in PostAcquireRequestState to force the Session for the context to be initialized. The article I am using as a template is posted here:[URL]In my case I am getting the following error:
[NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineModuleStepContainer.GetEventCount(RequestNotification notification, Boolean isPostEvent) +30 System.Web.PipelineStepManager.ResumeSteps(Exception error) +1112 System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +113 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +616
I believe that this error implies a problem with attempting to attach an event handler multiple times. I am aware that the modules Init function can be called more than once and have set a static initialization flag which ensures that I will only ever attach the event handler once.In the most condensed form my code is as follows:
public class HttpModule : IHttpModule, IRequiresSessionState
I'm still trying to resolve a problem with relative links on a page that uses URL routing. The relative links work find when running from Visual Studio, but fail when deployed to a shared hosting account.I'm told that the difference is that Development Server handles all requests through ASP.NET handler but IIS7 doesn't. The result is that URLs with no extension are considered folders on my test machine, and filenames on the shared hosting account. That breaks the relative links.
It was suggested that I do wildcard mapping to IIS7. But I can't make random changes to the shared server machine. I also have concerns about routing everything through IIS, graphics files, style sheets, javascript files, etc. In addition, I also tried adding a <base> tag, which fixed this issue but broke other links on the page.
So I'm left with two questions.
1. If IIS isn't processing files without an extension, then how does my routed page display as an ASP.NET page?
2. What I'd really like to do is specify in my web.config that all files with no extension be handled the way they're handled when running from Visual Studio. I don't suppose that's possible.
[FYI - Posted the same thing over at StackOverflow]I've used the UrlRewriting.Net module for a couple years now without any problems in Windows XP and Windows 2003. I just recently upgraded my home PC to Windows 7 and started developing a new website.The plan was to use .html extensions and rewrite them to their .aspx counterparts using the UrlRewriting.Net module. Everythingworks flawlessly in VWD 2008, but when I try running it through IIS7 it is a different story.
When I try to access a page via the .html rewrite I can no longer access Page.User; it keeps returning null. If I hit the page using it's .aspx extension, Page.User is correctly populated. I should also mention that I have a LoginView controller in my Master Page and it suffers from the same symptoms: When accessing via .html extension it shows the AnonyousTemplate; When using .aspx extension it properly shows the LoggedInTemplate. I'm guessing the two are related.[Note: I've also tried extensionless URLs and they exhibit the same problem]The only way I've gotten it to work is to switch the application pool to Classic, which then requires me to add an ASP.Net ddl handler for the .html extension [otherwise it is handled by the StaticFileHandler and comes up as a 404 error]. However, I'd like my web app to run properly for people without having to fiddle around with IIS.
So I am left with several questions:Does anyone have ideas as to why Page.User always equals null for .html => .aspx rewritten pages?Why does it work in VWD 2008, but not IIS7? What changed from IIS6 => IIS7 that could have caused this? Any other thoughts on workarounds?[Note: I just tried a .aspx => .aspx rewrite and it did not exhibit the problem. Not really what I want, but thought I should mention it.]
the purpose of this HttpModule? It's showing up on my HttpModuleCollection list, but I don't know what's it's for.System.ServiceModel.Activation.HttpModule
I am trying to implement URL rewriting technique in my Web application.I have found some articles on net 2 rewrite URL. But i m not able to understand. tell me any API or DLL which will take care of all url rewriting techniques in my Web applications.
I have heard something abt UrlRewriter.ddl . But i have not used it yet. provide me the easiest way to do that. If any sample application is there then it will be better ti understand
As i know that asp.net fulfill all the requirements for any web application but what are the ground rules for creating custom httphandler and httpmodule in asp.net.Edit:For example I want to fetch image from database then what i should i use httphandler or normally read image from database.If httphandler then why?
I am implementing HttpModule for compressing request.Below is the codee for HttpModule:
public class Global : IHttpModule { public void Init(HttpApplication app) {[code]....
It's able to intercept and compress js and css in the development web server but when i run it from IIS 5.1 it is not able to compress js and css files.
I have custom redirection implemented in a module. Do I have to modify each config for all sites or is there a more general approach?Also, I have files in App_Data for this module, which would cause replication.
I'm implementing a simple HttpModule, where I want some code to run when the web application is started. But I'm surprised to find that the Application_Start event I would normally use from Global.asax is not available from a HttpModule. Is that correct, or am I missing something here?
How do I hook into the Application_Start event from an HttpModule?
I'm considering making use of an HttpModule for localization purposes (based on the example in this article) - but I'm curious, is this safe?
Here's the code, for reference:
public class CookieLocalizationModule : IHttpModule { public void Dispose() { }
[code]....
I was under the impression that multiple threads could potentially service a web request. Is it safe to set the Current/Current UI Cultures in an HttpModule like this and have it respected for the life of the web request regardless of how many threads are involved in servicing it?
I am trying to implement a custom HTTPModule for ASP.NET. I have a very simple html page with an image in it and an HTTPModule that hooks into the BeginRequest event. When I debug with Visual Studio's dev web server, my module is called twice: one for the initial page request, then once for the image request. This is what I expected. However, when I deploy my application to IIS, the module is only being called once for the page request.
I want to save each request to the website. In general I want to include the following information: User IP, The web site url, user-if-exist, date-time. Response time, response success-failed status. Is it reasonable to collect the 1 and 2 in the same action? (like same HttpModule)? Do you know about any existing structure that I can follow that track every request/response-status to the website? The data need to be logged to sql server.
I could use late events such as EndRequest and put inside Response.Write but this way whatever I'm adding would come after the /html tag and the HTML won't be well formed.
I have an HttpModule and I'd like to choose the HttpHandler for the current request, is that possible? Also web.config is not an option because the condition is not based on path or extension. My googling skills have failed me, no matter what keywords I use all the results are "IHttpHandler vs IHttpModule".
I have written a HttpModule for our site which generally accepts requests and checks for specific file extensions as well as the value of a specific session variable. Is it possible to detect the first request in a session?
