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?

HttpHandlers / Modules :: Files Won't Download From Website When The Site Has A Custom HTTP Handler Mapped

Nov 28, 2010

When I have a HttpHandler class in C#/ASP.NET mapped to a file extension in IIS any file with that extension fails to download/display in web browsers (it's downloaded as a 0-byte file in some browsers and nothing at all in other browsers). After removing the application mapping for the HttpHandler in IIS so it doesn't call the IHttpHandler class in C#, the web browser downloads the file successfully.

This was tested with an IHttpHandler class in C# that has an empty ProcessRequest method.

HttpHandlers / Modules :: Piping Uploaded File To Somewhere Else

Feb 9, 2011

I am having a specific requirement of which I am not sure it is even possible to do but I have read somewhere in the past few days that similar to what I am trying to achieve shoud be done by writing a custom HttpHandler (or module?). Basically, I currently have a simple aspx page that accepts a file upload and forwards it to another URL (after doing some checking). The way this currently works is that my Page_Loaded gets called only after the entire file is uploaded.

What I am looking to achieve is get a hold of an uploaded file Stream early on as soon as request headers are processed so I could do some sort of piping froim the uploaded file Stream to my destination Stream. With large files this should be extra beneficial because there is no waiting time for the large file to get uploaded and my gut feeling tells me this way the memory footprint should also be lower. What I need is a forward-only Stream. No seeking needed. Therefore, I don't need to manage the entire uploaded file at some point in time. I just want to send the bytes as soon as they are received (with some lightweight processing in between).

HttpHandlers / Modules :: Downloading File Not Working With URL Rewriting?

Mar 21, 2011

I have implemented URL rewritting in my application. I did it in Application_BeginRequest located in Global.asax. My url rewritting in working fine. Now in order to maintain rewritting during post back.

I have added code line this.Form.Action = Request.RawUrl; in page load event in order to maintain rewritten URL during post back. When I am adding below code on image button click to download file it doesn't work. It says "Internet explorer cannot display webpage". When I am removing line this.Form.Action = Request.RawUrl; from page load then downloading file will start working but URL rewritting will not work on postback.

FileInfo objFi = new FileInfo(Server.MapPath(filepath));
this.Form.Action = Request.RawUrl;
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + objFi.Name);
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.AddHeader("Content-Length", objFi.Length.ToString());
HttpContext.Current.Response.ContentType = "application/octet-stream";
