The (non-UMN-mapserver based) WFS is public, and I am acting as a WFS
client, merely retrieving data. Maybe it's just the HTTP GET request
that was misspelled or incomplete.
This was my request:
http://geoportal.geodaten.sachsen-anhalt.de/geodatenportal/servlet/gtEntryPoint?&REQUEST=GetFeature&VERSION=1.0.0&SERVICE=WFS&TYPENAME=featureSet_704&BBOX=4400161.55779751,5779082.69612775,4502841.70515686,5881251.07072079&MAXFEATURES=100

Are these the correct URL parameters?
