[Zope] Re: exUserFolder and PAM - caching?

This is the zope mechanism, and indeed the http mechanism. Basic Auth
is sent for every page as well.

That's why remote things are best done with persistent sources ala an PAM
AuthSource, where you can cache user stuff (the IMAP/POP sources also
do this).

You could also I guess set a property on yourself or dummy object with 
username as the key and the last time checked, so you can avoid the 
overhead if last checked was within 5 minutes say.

It's trivial to convert one of the other AuthSources, if you've already
got an External Method to do the hard work, then you don't even need
have proxy roles d;)

Actually converting usAuthSource would be the easiest, since it's basically
empty already, and it heavily commented.
