Problems with Zip+IE6

Hi all! I have a problem with zip files and Internet Explorer 6. I try to send to the user a dinamically generated zip file writting the http headers and using file_put_contents for the zip content. It works fine when downloading the file with firefox, opera, etc... even it works well if I download the file with internet explorer and then open it with any zip tool. The problem comes when I try to directly open the file from the URL using IE6. I found this is a known bug of IE (several versions) in windows XP: http://support.microsoft.com/kb/308090 Does anybody know any way to workaround this problem? I found a couple workarounds in forums over there and I tried them, but unfortunately they didn't work: 1 - To change the mimetype (when writting http headers) from "application/zip" that I used before to "application/x-zip-compressed" 2 - To not use MOD_DEFLATE in apache2 (I was not using it really...) Any idea?? Thanks a lot!
