File download error in javascript

[Vijay Chandran]

Dear Friends,

I am trying to write a file download app. The file to be downloaded is a plain text file. I'm using the following JavaScript function, which will hit the server and get the file content.

window.open(url, target="_blank");

A new window is opened but when i'm getting an error response like this:

Internet explorer cannot download somefile from localhost.

I'm setting the following headers in the HTTP response at the server side:

response.setContentType("text/plain");
response.setHeader("Content-disposition", "attachment;filename="+fileName);
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");

My browser version is IE 8. This is working in latest version of chrome.

Please help in resolving the issue. Also, how to get Open/Save/Cancel dialog box when window.open is triggered and the response is obtained from the server?

Thanks,
Vijay
