Hi Mark, Under normal requesting circumstances (not using the squid proxy) the MIME types show up correctly, and this is confirmed with the output from the site you recommended. I tried using a different machine and squid performs properly, indicating the correct MIME types and referring to the correct IP address of the originally requested web server. There are a lot of variances between the correctly performing machine and the incorrectly performing one, and I'm trying to chase them down one at a time. In the meantime, if anyone has ever run into this problem before or is willing to help me chase down this issue, I'd appreciate it. -Gary -----Original Message----- From: Mark Elsen [mailto:mark.elsen@xxxxxxxxx] Sent: Friday, November 11, 2005 11:46 AM To: Gary Buckmaster Cc: squid-users@xxxxxxxxxxxxxxx Subject: Re: Squid mishandling certain kinds of media types > I have a single squid box running FreeBSD that is behaving very strangely. > With certain types of media files, most notably mp3, ra and wmv files, squid > lists them as mime type text/html.

Check this out with : http://web-sniffer.net/ If squid requests an object from a remote webserver then logic tells that the source address of the requestor is the ip address of the SQUID box. M.
