Noted. Cache-control is new to me, so I'm starting with recommendations I discover.
Also, is mod_deflate installed / enabled? I'd like to take advantage of Gzip's compression, but am not noticing a difference when I insert the following into my personal root level .htaccess:
<IfModule mod_deflate.c>
<FilesMatch "\.(js|css)$">
SetOutputFilter DEFLATE
</FilesMatch>
</IfModule>
Thanks,
