look http://wordpress.org/support/topic/192864?replies=3 .
what is problem? should not mod_deflate automatically leave url that sends in header that content is gzipped? and mod_deflate does not automatically leave them but deflate all?
let i show my mod_deflate server-wide configuration:
# these are known to be safe with MSIE 6
AddOutputFilterByType DEFLATE text/html text/plain text/xml
# everything else may cause problems with MSIE 6
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/rss+xml
may be it is possible to delete only line with text/html for super-cache to work?
unfortunately, as i know, it is impossible to turn off gzipping of text/html only or all only in one domain/vhost/site .>update: it seems to be impossible turn off what is turned on with AddOutputFilterByType which work with mime types, but there are AddOutputFilter and RemoveOutputFilter that work with file extension.< also it was said to me in httpd irc channel of freenode like that mod_deflate is quite old technology , and there is other technology, but i still do not use it, i tried once, but could not do or understand something. >update : indeed, it is deprecated, see http://httpd.apache.org/docs/2.2/mod/core.html#addoutputfilterbytype <
