hello .. somehow the cache seems now to work at all. even ig clobally and vhost based enabled there is never a X Header about a cache hit. however the real time stats showing about 1% of the pages beeing cached. can someone may point me in the right direction ? all the pages i checked however have this returned headers: Code: HTTP/1.1 200 OK Transfer-Encoding: chunked Date: Fri, 13 Dec 2013 03:24:55 GMT Server: LiteSpeed Connection: close X-Powered-By: PHP/5.4.4 Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Content-Type: text/html global config: Code: Enable Cache - no Cache Request with Query String - yes Virtual host config Code: Enable Cache - Yes Cache Request with Query String - yes htaccess Code: Options +FollowSymlinks RewriteEngine on RewriteRule .* - [E=Cache-Control:max-age=36] RewriteCond $1 !^(index\.php|lib/|i3/|tmp/|static/|theme/|robots\.txt|favicon\.ico) RewriteRule ^(.*)?$ index.php?go=$1 [L,E=Cache-Control:max-age=39] everything seems very straight forward any ideas ?
