[Mapserver-users] Passing CGI variables

[David Mitchell]

Dharani,

If you want you can call mapserv directly as you wish but you have to 
first set the QUERY_STRING and REQUEST_METHOD environment variables to 
trick it into thinking it is being accessed through IIS:

REQUEST_METHOD=GET
QUERY_STRING="zoomdir=1&zoomsize=2..."
C:/ms4w/apache/cgi-bin/mapserv_40.exe

That is all that IIS does anyway (not strictly true, IIS sets a few more 
variables and does a bit of house-keeping, but essentially the same). If 
your map has a template then the image will be in your temp folder and 
the std output of mapserv.exe will be the webpage (which you can throw 
away essentially).
