I am using w3 total cache and its compatibility check gave me following error
mod_deflate: Not detected (required for disk enhanced Page Cache and Browser Cache) mod_env: Not detected (required for disk enhanced Page Cache and Browser Cache) mod_expires: Not detected (required for disk enhanced Page Cache and Browser Cache) mod_filter: Not detected (required for disk enhanced Page Cache and Browser Cache) mod_ext_filter: Not detected (required for disk enhanced Page Cache and Browser Cache) mod_headers: Not detected (required for disk enhanced Page Cache and Browser Cache) mod_mime: Not detected (required for disk enhanced Page Cache and Browser Cache) mod_rewrite: Not detected (required for disk enhanced Page Cache and Browser Cache) mod_setenvif: Not detected (required for disk enhanced Page Cache and Browser Cache)
When I run:
apachectl -t -D DUMP_MODULES |grep setenvif setenvif_module (shared) apachectl -t -D DUMP_MODULES |grep expires expires_module (shared)
In webmin > apache, I have checked and all the required modules are enabled but not detected. Do I need to enable them for vhost file also. If yes, then please provide me detailed instruction about it.
