[mapserver-users] IIS and mapfiles and also GDAL

[Chris Jackson]

Hi Brent

Thanks for the quick answers, the new rewriting rules (with reverse proxy)
have worked well with Tomcat on port 8080 - no more isapi dlls!  What you
listed for Mapnik is essentially like mine, what I am not sure is what other
GDAL configuration is needed on the box - just an environment variable or
some other setting in the mapfile...?

Thanks

Chris
