C# - Response.Redirect Causes Download Of The Swf?
Feb 20, 2010
I have a flash image slider with a button below each image. When i press that button, the user is redirected to a new page where i add that image product to my cart. The problem is that after doing the adding, i want to redirect the user back to the initial page.
note that in Firefox is working fine but in IE or Chrome it is DOWNLOADING the swf...If i comment Response.Redict(...) the user remains on this page so the click button is working well, only the redirect seems to be the problem.
Edit: The problem seems to be that Request.UrlReferrer keeps as link not the initial page containing the swf but the swf itself.
So, instead of doing redirect to:[URL] if does redirect to the swf contained on the Index.aspx page[URL]
Solved: with a session variable where i keep the initial page's url

I am using some code similar to the code below to open a word document on my ASP.net app. Once the file has been downloaded and opened I then want to either redirect to another page or refresh the screen but nothing works after response.end and if i add it before response.end the browser never downloads the file?
I'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?
I want to redirect to "~/City/Göteborg", but if I just write Response.Redirect("~/City/Göteborg"); I will end up with an ugly URL in the address-bar like this: http://www.mysite.com/City/G%c3%b6teborg..
So my question is how to redirect to obtain a clean url like http://www.mysite.com/City/Göteborg?

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 have following function which is called from a button click event

I am working on a website that I inherited (ASP.NET and C#), and I noticed that in almost EVERY method in the code behind of the project pages (except some helper methods), the original author uses Response.Redirect() to redirect to a page (typically home.aspx, but not always).
What is the purpose of doing this? It seems unneeded to me - at least it doesn't appear to change anything the website is doing if I keep it in or remove it.
On an ASP.net site at my place of work, the following chunk of code is responsible for handling file downloads (NOTE: Response.TransmitFile is not used here because the contents of the download are being streamed from a zip file):
[code]....
I've just read about the 'buffer' property of the Response object. If I set that to false, will that prevent the Response.BinaryWrite() calls from buffering the data in memory? In general, what is a good way to limit memory usage in this situation? Perhaps I should stream from the zip to a temporary file, then call Response.TransmitFile()?
EDIT: In addition to possible solutions, I'm very interested in explanations of the memory usage issue present in the code above. Why would this consume far more than 1MB, even though Response.Flush is called on every loop iteration? Is it just the unnecessary heap allocation that occurs on every loop iteration (and doesn't get GC'd right away), or is there something else at work?
I'm working on some code that generates an Excel spreadsheet server-side and then downloads it to the user. I'm using ExcelPackage to generate the file.
The generation is working just fine. I can open the generated files using Excel 2007 with no issues. But, I'm having trouble downloading the file with Response.TransmitFile().
Right now, I have the following code:
//Generate the file using ExcelPackage string fileName = generateExcelFile(dataList, "MyReportData"); Response.AddHeader("content-disposition", "attachment;filename=FileName.xls"); Response.ContentType = "application/vnd.xls" Response.Charset = ""; Response.TransmitFile(fileName);
When Excel 2007 opens the file downloaded as above, it gives the "file format doesn't match extension" warning. After clicking past the warning, Excel displays the raw xml contents of the file. If I change the file extension, like so Response.AddHeader("content-disposition", "attachment;filename=FileName.xlsx"); Excel 2007 gives an "Excel found unreadable content in the file" error, followed by a dialog that offers to locate a converter on the web. If I click "no" on this dialog, Excel is able to load the data.
I've also experimented with different MIME types, like application/vnd.ms-excel and application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, combined with file extensions of .xls and .xlsx. All combinations result in one of the two behaviors mentioned above. What is the correct combination of file extension and MIME type to use in this scenario? What else could cause this failure, other than an improper MIME type or extension? FYI, this is occurring with Visual Studio's built-in development web server. I haven't yet tried this with IIS.
I recently upgraded a web app to ASP.NET 4.0 , but I have to downgrade it back to 2.0, because the Response.Redirect from another web app, which is in ASP.NET 2.0, did not work.
I'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?
I am working with ASP.net MVC 2 framework, for multiple sites. We have a base site and then sub sites that inherit from a "Core" site that contains 90% of the functionality that the sub sites will use.
In one of the controllers, I am saving some data, adding a UI message to the tempData and then using Response.Redirect.
The redirect works, but the tempdata is empty after the redirect.
I have tried returning "RedirectToAction" and "RedirectToRoute" with the same routing location and while it populates the TempData, the redirect doesn't happen lol..
So I guess in short, is there a way to get tempdata working when using a standard Response.Redirect?
Is it possible to pass on variables in response.redirect in a query string kind of way (without using form and submit).
If yes, what is the format?
I want to pass some variable (from a text box) from a classic asp page to .aspx page and this is what I am trying to do (I could not use session variables since classic asp and .NET asp share different sessions)-
I've just finished reading URL vs. URI vs. URN, in More Concise Terms, and it's really helped understand the distinction between the three terms. Since then I've skimmed the RFC2141 and RFC2616 specs and Microsoft's Response.Redirect Method documentation in an effort to answer the following question confidently.
Given this line of code:
Response.Redirect("~/Foo.aspx");
And this resulting HTTP response (trimmed for context):
I am using a gridview to display (open or save) files that have been uploaded into a SQL 2005 server. I have a templatefield within the gridview that contains a linkbutton that does a postback to GetUploadedFile.aspx that then fires the response.binarywrite() code. The code seems to work fine and opens/saves the files correctly. But once this has completed and I try and click on another button on the page, instead of doing the appropriate action it re-fires the getuploadedfile.aspx binarywrite code and opens up the "Open/Save/Cancel" dialog again.
