[Geomoose-users] Best way to refresh in GM?

Wed Oct 31 14:33:55 PDT 2012

Bob,

  Your code won't do anything; it sets the FILTER for that execution of 
PHP, sends some XML, then exits.  Whatever you get PHP to do is not 
persistent between executions (unless it writes a file).

It depends on your intended workflow, etc...

Best Regards,
Brent Fraser
