Point 1: Squid does not do that. Does not use mime.types at all.

Content-Type headers are passed through unchanged from what is received
unless administratively changed by header_replace.

Point 2: Squid does not accept mime types in the refresh_pattern
directive.

Are you _sure_ that:
 * the PAC file is not cached with old headers from before your changes?
 * the PAC file is actually being fetched from the web server you are
expecting?
 * this is an official build of Squid?
 * nobody has applied third-party patches to it?
(none of the official Gentoo patches change mime.types.
http://sources.gentoo.org/viewcvs.py/gentoo-x86/net-proxy/squid/files/)

What headers does this produce when run on the Squid box?
  squidclient -v -h wpad -p 80 /wpad.dat

The official releases of Squid pass content-type headers through
unchanged. Something is broken.
