Really wonderful. Its running and I got the /temp image created . cool 
thing. could you elaborate on how to set the REQUEST_METHOD etc 
programmatically ?MY aim is to totally move the mapserv exe and its 
dependencies out of IIS/ apache folders . I dont want to keep  IIS or apache 
running . I hope you have seen my method at my message on vb.net usage
http://mapserver.gis.umn.edu/cgi-bin/wilma_hiliter/mapserver-users/0404/msg00395.html?line=20#hilite
I am lacking to find the methods to find the methods to set the environment 
variables programmatically .
with regards and thanks in advance
