Hello,

# curl -I -H 'Accept-Encoding: gzip,deflate' http://mydomain.com

so i see it appears to be enabled in apache, but i cant find it in httpd.conf, any mod deflate log or anything to veriffy it does the job? I see content is gzip encoded, but it non necesarrily mean that its done by mod_deflate? thx
