Creating a designated graphics file

[Steven Monai]

Chip:

How about using the mapserv CGI in "map" mode? From within an ASP script,
you should be able to send an HTTP GET request (with all relevant
parameters, particularly "mode=map") to the mapserv CGI, and then save its
output (the map image) to a file of your choice.
