[Mapserver-users] DHTML Navigation Tools for MapScript

[Joe Bussell]

In truth, a great deal of the effort that went into the current version 
of TrafficDodger was an exercise in cross-browser DHTML.  The result is 
useful to us, but it relies on our underlying PERL based CGI.  We wrap 
MapServer entirely, thus allowing the level of control that we wanted. 
I wouldn't mind generalizing what has been done to contribute to such an 
effort.  I believe that our product could be improved by leveraging some 
synergy with other folks doing similar development.  I would be willing 
to contribute to this effort.

Cordially,
