CGI error.

Fri Jun 17 07:46:29 EDT 2005

Hello Siddarth,

You can enable MapServer debugging by setting DEBUG ON in the .map 
file for the MAP, LAYER and CLASS objects you want to debug and adding 
a LOG parameter in the WEB object pointing to a file where the log 
info will be stored (you can use abdolute or relative paths, this file 
needs write access for the IUSR).

See also:
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?DebuggingMapserver
http://mapserver.gis.umn.edu/doc44/mapfile-reference.html (serach for 
DEBUG and LOG)

Now you will get a log file with MapServer log info.

Another handy tool to monitor running programs is filemon from 
www.sysinternals.com

Install it and run it and don't forget to use a filter on the name of 
your MapServer executable or you will have to dig to giant loads of 
log info (sometimes necessary though to not use a filter).

Regards,

Emil
