Question

I have a classic ASP page that is setting the ContentType to “text/plain” and streaming the bytes of a text file to the browser. However, Internet Explorer 7 (and presumably other versions) is ignoring this and instead of opening the darn text document in a monospaced font as it should it’s prompting “Do you want to save or open this file?” because it’s coming from a web page ending in “.asp”.

When I set .txt files to be run through the ASP parser and then make a copy of my .asp page with the extension .txt, everything works fine.

I’ve examined the headers in Firebug on FF and know I’m setting the content-type correctly and not missing any other important headers.

Is there any other technique to preventing IE from using the file extension to change how it responds?

This is nonsense! Respect my content-type, you third-rate browser!

Answer 1

Try changing the filename (with extension) using the content disposition header

Something like Response.AddHeader(“Content-Disposition”, “inline;filename=”File.txt”)
And you already said the content type header is being set correctly so that should do it.
