exception in WMS GetMap

[Bart van den Eijnden]

Hi Nuno,

to get the request you need a Mapserver compiled with DEBUG info (MSDEBUG
when you do mapserv -v), and DEBUG ON on your LAYER definition.

You can also perform the following trick on Windows: put the remote server
in your Windows hosts file:

\WINNT\system32\drivers\etc\hosts

with a reference to localhost, eg:

localhost iceds.ge.ucl.ac.uk

That way you can check the Apache access log on your server to see what
the Mapserver WMS request looked like.

Hope this helps.

Best regards,
Bart
