 * I have wp-rocket installed & wp-rocket is giving a warning msg that:
 * (WP Rocket: The following plugins are not compatible with this plugin and may
   cause unexpected results:
    WP-FFPC)
 * 1. Will it cause any problem?
    2. I tested that wp-ffpc is working or not, and
   i am not getting “X-Cache-Engine”…what to do? But i can see that apc, apcu & 
   memcached options are active in wp-ffpc settings.

 * 1, I’ve never heard of wp-rocket. You need to ask this from wp-rocket author,
   since it was not me who put that message in there.
 * 2, Please try to debug it. If you need my help, give me specific context, like
   which engine you’re running, turn on debug log, and see what the log says, and
   so on.

 * Now, its working. I have checked it via chrome View Tools. Thanks for this great
   app.
 * 1. Can i use w3 total cache along with your plugin?
    2. Caching is better with
   memcached or APC or APCu ?

 * I’m glad it’s fine now.
 * 1, you can, but I’d recommend to use only the non-overlapping functionalities
   of w3.
 * 2, depends on your setup. APCu only plays well with php 5.4+, for 5.3-, use APC.
   For me, php 5.6 with APCu is the fastest at the moment.
