[mapguide-internals] Please review AjaxViewerPingServer.patch

[Christine Bao]

Hi all,

     I've attached a patch http://trac.osgeo.org/mapguide/attachment/ticket/1026/AjaxViewerPingServer.patch. Please review. Thank you.

     The comments for this patch:
                This submission makes Ajax viewer pinging server to keep alive.
Once Ajax viewer loaded, it will get server time out time n seconds, and ping server at a time interval n/5 seconds. If the pinging fails after 6 times, it will stop.

Thanks & regards,
Christine
