I have WP Super Cache enabled but am confused about the sites' behavior on tools.pingdom.com.
In view source, I see the WP Super Cache comments in the footer. Somewhere I saw a reference to comments are supposed to be in the header too but they are not there. The site does load faster so I assume that it is working.
However, when I go to tools.pingdom.com, each page element loads separately like WP Super Cache isn't active. Can someone explain this to me?
