[mapserver-users] WMS call with layer names containing a space.

[TC Haddad]

When querying the TIGER server directly from a browser, the first and third
styles of request both work, while the option with the "+" does not. So
those are the 2 options the server will accept.

I guess Mapserver prefers no space in a name, or a "+" to designate space,
so you might be stuck.

As a best practice, they really should have the version with a space in the
Title rather than the Name, but you can't fix that from your end.
