Expires Header?

I have your plugin installed. I am getting a message of GTmetrix regarding adding expired headers. Sorry for my ignorance on this but I’m assuming that is something which WPFC has nothing to do with correct? I mean there is not an option to add expired header.

Another plugin for Far Future Expire Headers had an option to enable Gzip compression. Since I have that selected on your plugin I would assume that I should not enable it on the other?

Thanks!
