[imp] an IMAP question about IMP

[Michael M Slusarz]

Quoting Marc Silver <marc.silver at uk.easynet.net>:

| Hi there,
| 
| My apologies if this is in the wrong place, but I'd like to find out the
| following:
| 
| Does IMP have to reauthenticate to an IMAP server for _EVERY_
| transaction, or does it keep some sort of persistent connection to the
| IMAP server?  That said, if it is 'persistent' what would happen if the
| IMAP session timed out?

IMP authenticates only once per *request* (i.e. once for every page load).  
Anything that is run out of this page load uses a global connection 
variable ($imp['stream']) to access the server... (well, this is not 
exactly true. there are some cases where we open more than 1 connection for 
various reasons).  Thus, when a page is finished loading, the IMAP 
connection must be closed.

There is no support for persistent connections (like MySQL persistent 
connections) in PHP for imap.
