[Mapserver-users] WMS using libCurl fails because of a wrong HTTP User Agent

[Norbert Schauerte-Lueke]

HI Tom,

This is the URL of the server. If I use the patch given from Daniel it 
works.
http://www.geoserver.nrw.de/GeoOgcWms1.3/servlet/GEPNRW
?VERSION=1.1.0&SERVICE=wms&REQUEST=GetMap&LA
YERS=GEPNRW:Gewerbe&STYLES=,,&SRS=EPSG:31466&
BBOX=2531220,5704038,2541515,5715184&WIDTH=700&H
EIGHT=500&FORMAT=image/png&TRANSPARENT=true&
EXCEPTIONS=application/vnd.ogc.se_inimage

The MapServer Software that is used comes form AED-Sicad. But I 
think they try to fix that problem.

Greetings Norbert.
