I have a few servers, one is new running Apache/2.2.13 and the others are currently running Apache/2.2.11 both have a statically built mod_deflate which shows up in `apachectl -l`, but I'm am unable to enable the deflate fliter on the servers running Apache/2.2.11.
On two of the servers (one 2.2.13 and one 2.2.11) I added SetOutputFilter DEFLATE at the bottom of a <Directory> block where AllowOverride is set above. This works well on 2.2.13 but gives the error " an unknown filter was not added: DEFLATE" in 2.2.11. I have also tried to set the filter inside a <Location /path/to/www> where the path matches what was set in the <Directory>. In all of these configurations on the 2.2.11 server i get the error and the content is not gziped. Even though it is deprecated i did try AddOutputFilterByType DEFLATE text/html and recieved the same errors. I took a quick look at the change log and while there have been mod_deflate changes between 2.2.11 and 2.2.13 i didn't see anything that would point to it being broken (and i highly doubht it is). Finally a question, do i need to upgrade these apache servers, or is there another way to enable deflate on the 2.2.11 systems. Thanks Jeff
