[mapserver-users] redrawing the map

Fri Apr 18 17:14:55 EDT 2008

right now, i have a nearly functional code.
This code is for zooming to a predetermined area.
the problem is that the map doesn't get redrawn when i use this script.
I found this script in the archive, and would like to know is there a line i
have to add in order to get it to redraw or refresh the map.
More importantly if this script is actually correct, any help is much
appreciated.
