enable x-cache just for License ?
 

Hello,
litespees have xcache, memchace etc
there are just for litespeed licence ?

xcache and memcached are sperate to the litespeed install xcache is a PHP module and memcached is a softwared with a PHP extension.

I don't think Litespeed will limit what PHP modules you wish to install, no matter what licence you choose (free or not).

Edit : Oops, just noticed this goes back to 2011 !
