Session or cache WEIRD problems

[eluser]jahbob[/eluser]
Yey I fixed, just added the

header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");

has was sad in the other topic...

But now no cache at all is avaible, anyone knows a better solution ?(At least now we know that is a cache problem)
