[Mod_gzip] Caching working with mozilla but not IE

[Auz]

I've run into this before. IE refuses to cache images if they're sent with a
Vary header, which mod_gzip sends. The solution (from this post on the list:
http://lists.over.net/pipermail/mod_gzip/2002-December/006776.html) is to
switch off the Vary header explicitly for images using this in your config:

  <Files ~ "\.(jpg|gif|png)$">
  mod_gzip_send_vary Off
  </Files>
