MVC :: Response.WriteSubstitution Does Not Work?
Jan 21, 2011
I am trying to write out some dynamic contents on a cached page with Response.WriteSubstitution but it doesn't work. Besides, HttpRuntime.Close() is not clearing my output cache. I read the following thread on MS Connect and was quite shocked.
"Due to a change in how ASP.NET MVC 2 views are rendered certain functionality will no longer work...". It seems kind of foolish to remove this feature. Can anyone explain how I should use output caching in ASP.NET MVC if I can't have dynamic portions of a cached page?

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?

The application is hosted in Windows Server 2008 with IIS7.
I have a button that calls a new webpage (asp.net page, ext .aspx) that contains
Response.OutputStream.Write(blahblahblah) which then should prompt a download box to allow user to save an image.
Now the page basically creates a stream and then is supposed to output the stream to the user using Response.Outputstream.Write.
Then the user is supposed to be prompted to open or save the document. This works fine in Firefox but it does not work with IE7 or 8
Also this exact same code works with IIS6 on a Windows 2003 server.
So the only differences is the IIS6 and Windows 2003 Server to IIS7 and Windows 2008 Server.
And what happens is when I clicked the button, the page did pop up but disappear 1-2 seconds later without
prompting the download box to the user.
Here is the code that launches for Reference
//e.g file = 123424_43535.jpeg
FileInfo myFile = new FileInfo(Server.MapPath("mapImage/") + file;
using(var fs = myFile.Open(FileMode.Open, FileAccess.Read))
{
byte[] buffer;
int read;
buffer = new byte[(int)fs.Length];
Response.AddHeader("Content-Disposition", "attachment;filename=" + file);
Response.ContentType = "application/x-force-download";
Response.AddHeader("Connection", "Keep-Alive");
Response.AddHeader("Content-Length", fs.Length.ToString());
while((read = fs.Read(buffer, 0, buffer.Length)) > 0)
{
this.Response.OutputStream.Write(buffer, 0, read);
}
}
Response.End();
I have tried to replace Response.AddHeader with Response.AppendHeader, however the result is still the same. Also, I have tried to replace the Response.ContentType with application/octet-stream and image/jpeg, I also faced the same result.
Is there any setting/modification on server/code that I need to look on?

I am trying to redirect to a page and send two values.
Now the second value is the value of a text box and If I type something one character or anything without space character then the redirect works but If I type two strings for second value or anything with a space then the redirected page hangs and shows a blank page. I am using-
Response.Redirect("Changes.aspx?id="+CustomerId+"&Req="+txtRequest.Text);
If I use value id= anything applicable and Req="A" then it works
but If I use value id= anything applicable and Req="A(space)B" then the next page hangs with a blank page.

What I have?I have a ASP.NET page which allows the user to download file a on a button click. User can select the file he wants from a list of available files (RadioButtonList) and clicks on download button to download it. (I should not provide link for each file that can be downloaded - this is the requirement).What I want?I want the user to download multiple files one by one by selecting the required radio button and clicking on the button.What problem am I facing?I can download the file for the first time properly. But, after downloading, if I select some other file and click on the button to download it, click event of the button does not post back and the second file will not be downloaded.I use the follwoing code on the button click event:
protected void btnDownload_Click(object sender, EventArgs e)
{
string viewXml = exporter.Export();
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=views.cov");
Response.AddHeader("Content-Length", viewXml.Length.ToString());
Response.ContentType = "text/plain";
Response.Write(viewXml);
Response.End();
}

I've followed the instructions in the two articles above, plus more and I still cannot get response.redirect to work. I am able to see the url of the page I am trying to redirect to in fiddler but the browser does not navigate to the page. I am using Cassini as a web server, could that be the problem?
Here is global.asax

We have a web application which is changing to a new page using response.redirect("MainMenuPage.aspx"). It is running under framework 3.5.
The code has been working for years on 2.0 and 3.5 running on Windows2003. Now we migrated it to 2008R2 we have some problems.
The code is running ok on Windows7 Visual Studio 2010 in debug mode.
On the server there is no error logged.
Symptom is that when the user is redirected to the main menu page, the hour glass comes on the browser and nothing else happens for about 1 hour, then the browser returns a dns error.
As this does not occur in debug and and there is no error on the server, it is quite difficult to see what the problem is, but we are fairly sure it is coming from the response.redirect line.

According to MSDN documentation, this is supposed to set the Cache header "Expires" to a certian value. A check of fiddler for the response from my handler indicates the Expires is being ignored. Is this a known bug? I see other posts where people have just given up with out an answer.

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.

I'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 am working on a multi-language web site. It is half English and half Portuguese. I have created forms that have portuguese values in it. These forms work perfectly on my desktop. I'm using Cassini as the development server. When I move them over to IIS, they are not loading properly. The text comes up all weird looking. I am declaring the culture in the page attribute: Culture="pt-BR"
