You don't, there aren't any good effects of saving the resource in a session.
mysql_connect() results in a disconnect from the sql server when the
php-script has been run.
mysql_pconnect() tries to keep the connection alive, but still do not save the
resource to a session, as you never know if the connection will stay alive to
the next php-script, so you need to rerun the mysql_pconnect(), it will check
if the connection is still alive, is so it won't do anything else, but if it
would be so it's dead, then it will reconnect to the sql-server.

You will have as many mysql_pconnect() in your code as you did have
mysql_connect(), but you will have less overhead.
