I had a similar problem that a dynamically generated PNG was re-requested when a user right clicks and does a 'save' (both in FF and IE). There was a GET request triggered after the initial POST that generated the image. We got around this by setting the mime type to application/unknown for the content. That way, IE and FF do not try to decode the content and do not try to 'support' it through plugins, external programs, etc. I think it just asks to save the file. I think I replied this in an earlier mail. But, either way, hope this helps.
