I think what Oleg is referring to is that search engines generally compare
the Last-Modified header before pulling in the whole file, to see if they
are the same or not ... php, unfortunately, sets that to now(), so as far
as SE's are concerned, every time they index is a new file :(
I'm going to play with mhonarc this week to see if I can get it to
properly set Last-Modified to Date based on the message itself ... that
will clean up that mess ...
Oleg, is there anything that I can put into <HEAD></HEAD> for this? To
avoid having to use PHP to do it?
