[Zope] GUF strange behavior

Hi! I have discovered that I was fighting the wrong fight, against GUF. After making a login, I get the old, good, login page again. If I reload the page, then I get the correct index_html page, instead of the login page. What is wrong with this? I put the "pragma" "no-cache" in a META tag in the header of the docLogin method, but I still needs a reload to get the right page, instead of the login page. Is it a Netscape bug? Is it a GUF bug? Is it my mistake? I'm using Zope 2.1.6, GUF 1-2-4 in a Linux 2.2.x box. TIA -- César A. K.
