[Mapserver-users] Zoom previous

[Chip Hankley]

>Does anyone already did a zoom previous function...

A low-tech way to do this that works a LOT of times is to simply use
the 'back' function inherent in the web-browser. You can simply apply
the javascript 'history.back()' to a button, and call it "zoom to
previous extent" or something. This is the equivalent of hitting the
'back' button.
