Hi,
I have heard about something called "If Modified Since" and it is some type of HTTP header that it is supposed to speed up your site. I have searched a lot, and have contacted Bluehost (my host) and I haven't figured it out. Could somebody tell me what "If Modified Since" is, and how to enable it? I have checked on FeedTheBot and Microsoft, and nobody says I have it enabled.

Thanks!
