=============

The default locations for ModPagespeedFileCachePath (/var/mod_pagespeedcache/) 
and ModPagespeedGeneratedFilePrefix (/var/mod_pagespeedfiles/) do not comply 
with the Linux Filesystem Hierarchy Standard (http://www.pathname.com/fhs/). 
Ideally, it should place its files in the locations mandated by the above 
standard. I'd suggest:

    ModPagespeedFileCachePath            "/var/cache/mod_pagespeed/"
    ModPagespeedGeneratedFilePrefix      "/var/lib/mod_pagespeed/"
