I want to find out exactly how long the Response sent to the user was, after the fact, for logging purposes. Is there any way to do this from an HttpModule in asp.net (in the PostRequestHandlerExecute event).
View 2 RepliesI'm looking at creating a simple URL shortening service for our corporate intranet, and I'm curious if anyone knows if there's a maximum length for URLs returned by ASP.NET's Response.Redirect method?
View 3 RepliesWhen the user tries to upload a file with a size more than 4 MB, the AsyncFileUpload control gives a Confirmation alert (with "OK"/"Cancel" button) with the following message "Server Response error: Maximum Request Lengh Exceeded". But when the User clicks the "OK" button a new window popups and shows the server error and on clicking the cancel button the AsyncFileUpload background color turns red. Here I am not sure why the control is showing a Confirmation alert instead of a simple alert message. Is it possible to change the Confirmation alert with the simple alert message? Basically I don't want the popup window to show the server error as it is happening currently. Also, is there a better way to handle the file size error and show apporiate error message to the users?

I have a static method that I use to control REST styled HTTP codes when my mvc application encounters an exception.
The method looks like:
[Code]....
This is static becuase then I can call it within an action or inside a filter. The problem I am having is that when I call RaiseException inside a filter, it stills goes into the requested action. Response.End() doesn't seem to have any effect. Any clues on how I can get Response.End() to work when called?
Is it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
View 5 RepliesI'm using Response.Filter in order to implement stream compression in accordance with HTTP Request Header Accept-Encoding
Here's the important stuff:
if (AcceptEncoding.Contains("deflate") || AcceptEncoding == "*")
{
HttpApp.Response.Filter = new DeflateStream(PreviousOutputStream, CompressionMode.Compress);
HttpApp.Response.AppendHeader("Content-Encoding", "deflate");
}
By and large this works as intended. However, I'm in a situation where I'm using an ActionResult on an MVC Controller to serve up files to the user agent:
Response.Clear();
Response.Headers["Content-Type"] = contentType;
Response.Headers["Content-Length"] = contentLength;
if (Request.QueryString["dl"] == "1")
{
Response.Headers["Content-Disposition"] = "attachment; filename=" + fileInfo.Name;
}
Response.Flush();
Response.TransmitFile(fileInfo.FullName);
To be more exact, the action method returns new EmptyResult() after the Response.TransmitFile() call. This works exactly as intended without the Response.Filter modification.
In this situation, the response entity reaches the user agent garbled and unintelligible. FireFox's Poster addon shows empty entities or jumbled entities coming back.
I have written simple HttpModule. context.Response.Output.Write is working fine. but not context.Response.Write().

I'm trying to port an ASP.NET MVC 1.0 / Visual Studio 2008 project to ASP.NET MVC RC 2 / Visual Studio 2010. The project is (and has always been) running on IIS 7.
Dynamic content (everything that's being delivered by controllers) works fine, but static content such as CSS / Javascript / Images gives me a "200 OK" response, a Content-Length of 0 and no content. It's as if all those files were entirely empty (I made sure the files are not empty though).
The static content is in a directory that I excluded from ASP.NET routing via IgnoreRoute.
It can't be a hidden 404 error since adding some garbage characters to the URL produces a reguar 404 error.
It doesn't seem to be related to filesystem permissions since I've already given everyone full access rights in the contents directory.
Edit: I just created a completely new ASP.NET MVC website from scratch and tried running that in IIS. It has exactly the same problem! So it's not really a problem of converting my project to MVC2 at all, it rather seems to be IIS that's causing the trouble. But what could possibly be the problem?

Code:
Code:

I'm trying to fix an issue with an application I'm supporting (I didn't write the code). The code takes an SSRS report and renders it in pdf format.

I read that the default length limit is 4MB. None of the reports by themselves are even over 350K. I'm wondering if this could be caused by a caching issue. I'm not an expert, so I need some guidance as to how best to solve the problem. I also want to understand why the issue is happening. note that only 2 reports are shown in the snippet - there are about 30+ reports in the full sub. edit - I tried the proposed solution, but it didn't help (I also tried the Fiddler route, but did not see anything glaring). I thought it might be best to clarify. The reports will run fine for a while, but the execution time gradually gets slower and slower until the application eventually displays the error.
