[users@httpd] an unknown filter was not added: GZIP

Hi Guys

I keep seeing this error message

an unknown filter was not added: GZIP

Google appears to be unhelpful.
Server version: Apache/2.2.16 (Debian)

Mod_deflate is on.

Thanks
Brent

Hi Tom

Thank you so much for replying.

A quick
grep  -r --exclude=*.{png,jpg,jpeg,flv,avi,swp,gif,sql,css,js,htm,html,xml,spc,tpl} --exclude=*cache* --exclude=sess_* --exclude-dir=sessions SetOutputFilter *
revealed the culprit .htaccess files.

Thank you very much.

mod_deflate provides the DEFLATE filter which implements the deflate
compression algorithm. It doesn't provide a GZIP filter.

Somewhere in your config you are trying to "SetOutputFilter GZIP" ?

Cheers
