Subject: mod/chat - Normal method now supports HTTP Keep-Alive - users pane
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=6169ea259af8674443e8d2cd2ece3b5e8d1b8a4b;p=moodle.git

mod/chat - Normal method now supports HTTP Keep-Alive - users pane

User's pane now also uses keepalives -- if the refresh freq is below
the disconnect timeout, then it is a win. Otherwise it wastes memory
at the server end.
