transbetty on "[Plugin: W3 Total Cache] Xcache caching any PHP, not just WordPress pages"

Hello,

I'm using Xcache together with WordPress and W3TC on some websites. What puzzless me is Xcache seems to cache any PHP file, not just parsed output for WordPress. Is this usual behaviour or are my Xcache settings wrong?

I realized the fact looking at Cacher tool, "List PHP" tab.

Is this normal behaviour?

Thanks, Betty
