That is because HTTP is a stateless protocol, there is no way for a web
server to maintain a connection to the IMAP server. I would suggest you
look into IMAPProxy.org (up-imapproxy), it caches the connections so you
don't get an authentication hit every time you navigate your email.

> Hello,

getting a bunch of the following in our logs:

> I am not sure if this is a problem with courier-imap or squirrelmail or
if this is a problem at all since there has been no user complaints.
Still, I would like to find our why. Any ideas? Strace output is
below. Perhaps it will help.
