[Plugin: W3 Total Cache] MaxCDN shows a high non-cache hit percentage

Got W3TC installed and working for quite some time. Page loads seem snappy so I thought everything working as it should.

We used MaxCDN pull (mirror). I recently discovered that the non-cache hit is 99% all the time. It should be very low because hits are served via cached version instead if the settings are correct.

MaxCDN told me that one of my pluggins is causing this
“This plugin is setting a certain “cookie”, and we assume there’s a cache miss when this cookie is set.”

I’m posting it here in case Frederick sees this or anyone ran into similar problems before.
