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

[Palle Due Larsen]

Here is what I would do: 
Make an asp script i.e. mapserv.asp. Pass it all the parameters 
mapserver needs + a service parameter. Have all the services stored in 
a configuration file, that says which mapfile goes with which service. 
Have all map files stored outside the website. Pass all parameters, 
except the service parameter on to mapserver + the map parameter. Grab 
the output, and pass it back. 
We do something similar with a perl script, it's quite easy in perl, it 
could be harder using asp.

Best regards
