Mapfile WMS connection string parsing problem for layer names with dots/periods (".")

[Havard Tveite]

While editing the connection string for my email, I must have
removed too much.  Sorry!  The problem persists though.
The "LAYERS=" was there originally:

CONNECTION "http://wms.server.org/wms_test?VERSION=1.1.1&SERVICE=WMS&REQUEST=GetMap&LAYERS=TEST.TEST&STYLES=&FORMAT=image/png"

Produces the following in the mapserver log file (slightly edited...):
Thu Jan  4 15:46:17 2007,23090,127.0.0.1,test-wms,0,261498.765626 6621607.187500 262014.390626 6622122.812500,261756.578126 6621865.000000,test ,msBuildWMSLayerURL(): WMS connection error. MapServer supports only WMS 1.0.0 to 1.1.1 (please verify the VERSION parameter in the connection string). <br>
msOWSParseVersionString(): WMS server error. Invalid version (1.1.1&SERVICE=WMS&REQUEST=GetMap&LAYERS=TEST.TEST&STYLES=&FORMAT=image/png). OWS version must be in the format 'x.y' or 'x.y.z' <br>


while
CONNECTION "wms.server.org/wms_test?VERSION=1.1.1&SERVICE=WMS&REQUEST=GetMap&LAYERS=TEST_TEST&STYLES=&FORMAT=image/png"

Gives me an inimage exception ("LAYER with ID TEST_TEST does not exist")
from the WMS server, as expected.


To reproduce the error one should only need to create a map file
with a WMS layer and a connection string that includes a layer name
with a "." in it.
