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

[Basques, Bob (CI-StPaul)]

I was hoping there might be some tricky way of fooling MapServer by encoding, etc.

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.

All,

I’m trying to use this WMS:

http://tigerweb.geo.census.gov/arcgis/services/TIGERweb/tigerWMS_ACS2015/MapServer/WMSServer?

Specifically, two layers, “Census Tracts” and “Census Tracts Labels”

I can open the service in just about everything, except Mapserver as a WMS client.  I’m assuming the problem is in how MapServer is sending it’s request.


I must be missing something obvious.


Thanks.
