[Mapserver-users] WMS Client on IIS with MS_MAPFILE variable problem

[Paul Spencer]

David, not sure if this is even supported on windows? But there is a
command line for sending the query string to the mapserv executable, one
reference to such is:

http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0306/msg00566.html

Not sure if you can access the GET parameters in wsh, if you can then
you could reconstruct the query string and add the query_string to the
run command, which would essentially do the same thing.

Cheers,

Paul
