[Mapserver-users] WMS Cllient for ArcView 3.X

This brings up an unrelated but important issue:
Mapserver when running in WMS mode should always report its errors in 
the proper OpenGIS XML format. I wonder why we got an error in 
text/html? Shane, are we always requesting our errors in XML, or are we 
just taking whatever the server provides us?
