Answer 1

dynamic create Iframe ,set the src to the download page loaction , append to the body.

function downloadInIFrame(fileId) { var url = "download.aspx?fileId=" + fileId; var iframe = document.createElement("iframe"); iframe.src = url; iframe.style.display = "none"; document.body.appendChild(iframe); }

those code works well for me.

Answer 2

It sounds like I problem I came accross with IE 8 only. When I was tracking down a solution I came across 2 solutions. One of them should correct this issue.

Just to let you know it is a fix on the client machine as it is how IE coded that causes the issue.

Answer 3

This issue is caused by a browser setting in Internet Explorer. In Internet Explorer go to Tools > options > Advanced options. In the section marked Security, locate and clear the Do not save encrypted pages to disk.

Answer 4

Just like rymo said set Cache-Control: private, If your response header happen to have the Pragma :no-cache, you also have to change it to Pragma: token .

Answer 5

if you using asp.net. remove the code with sets cache

Comment the following

       Response.Clear();
   Response.Buffer = true;
   Response.Charset = "";
   **//Response.Cache.SetCacheability(HttpCacheability.NoCache);**
   Response.ContentType = contentType;
   Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName);
   Response.BinaryWrite(bytes);
   Response.Flush();
   Response.End();

Answer 6

We had this same issue with IE8 using an MVC controller tagged with NoCache. This sets Response.Cache.SetNoStore which breaks file downloads in IE.

To resolve - you can reset the Http Cache Policy via reflection.
