Still no luck... I read through that site and can't figure it out either. I guess I'd better give some more information too, if it might help:
actual website: http://www.riumplus.com
/riumplus.com/.htaccess chmod:744, contents:
mod_gzip_item_include mime ^text/.*
mod_gzip_item_exclude mime ^application/pdf$
mod_gzip_item_exclude mime ^image/.*$
ErrorDocument 403 /forbidden.html
ErrorDocument 404 /missing.html
ErrorDocument 500 /scripterror.html
example file: /riumplus.com/index.html chmod:777
I've been testing it with a handful of online gzip checkers, one such one being at http://www.whatsmyip.org/mod_gzip_test/. They always show up negative, though.
What am I doing wrong?
