[Mapserver-users] change parameters via URL

[John Hagstrand]

Hi Jan,

In a previous message you told me about the feature that allows me to
change mapfile parameters on the URL.

I've been trying to do this, but I'm using the WMS version.

http://localhost/saveantioch/map/bin/mapserv.exe?map=c:\John\Interland\SaveAntioch\Production\Map\sa.map&map_devHilite_class_expression=([Id]eq2)&VERSION=1.1.0&REQUEST=GetMap&BBOX=1035257,2093349,1090581,2123975&LAYERS=,city,wetlands,water,hiways,roads,rail,streets,fpbound,statpark,parcels,dev&width=690&height=382

I realize this syntax is not standard WMS so I'm wondering if this will be 
possible.  I really do need a way to dynamically select certain polygons 
out of specified layers.

Can you help?
Thanks
John
