ok, so I removed the "Pragma: no-cache". With IE it looks fine now, and if I repeat it two times it always gets is from elog and not from the cache due to the "Expires:" statement. The "no-cache" came from old days when some browsers did not yet support the "Expires" tag. I hope that this is better now, so let's see when we get the first complaints. The modification is in SVN revision 2265.
