[LON-CAPA-admin] Cookie problems but still switched?

I have not seen problems with LON-CAPA, but then we have a VERY simple setup at the college. What I have seen though is Safari, and indeed Mac OS X not allow write on redirection. By this I mean that it will allow an initial server connection to write a cookie, or write a pointer in some file for a proxy service, but if it is then followed by a redirection it will not allow the NEW server to write, or it will ignore what it tries to write. It usually seems security related.
Lately I have been having better luck with Firefox 10 ESR.
Sorry I can not offer more help.
