I'm trying to add two things:
ExpiresActive On ExpiresByType text/css "access plus 30 day"
AddOutputFilterByType DEFLATE text/css
but in either case it does not show up compressed or have a later expiration date. I used Firebug to check, and cleared the cache to make sure. The mime type is in there. Thanks.
Ive also added the mime type manually but it doesn't change anything:
AddType text/css css
