Please include your mapfile and the wfs-request-testlayer.xml file to
reproduce. I'm confused by the mapfile you posted yesterday that uses
epsg:25832 and the fact that GDAL through mapserver would issue a
GetFeature in EPSG:3857 as suggested below. I can't see how that could
happen (given the MapServer/GDAL integration, GDAL should always request
in the native SRS of the layer and MapServer will do the reprojection to
the SRSNAME of the WFS request)
But as Daniel suggested using the CONNECTION WFS is probably a better
way of doing what you want

So here is the working not working setup. Unfortunately the working
OGR WFS client layers are all private so I can not share them.
This call delivers objects as expected:
http://localhost:8181/cgi-bin/mapserv?map=/var/www/html/wfs.map&SRSNAME=EPSG:3857&SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&Maxfeatures=10&TYPENAME=TestLayer
This one, too:
http://localhost:8181/cgi-bin/mapserv?map=/var/www/html/wfs.map&SRSNAME=EPSG:3857&SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&Maxfeatures=10&TYPENAME=TestLayer
Data is delivered in the correct srs (verified manually with QGIS).
This call doesn't work as described before as BBOX is not transmitted
to external server:
http://localhost:8181/cgi-bin/mapserv?map=/var/www/html/wfs.map&SRSNAME=EPSG:3857&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&BBOX=791880.72463009,6321925.37255709,792929.63787777,6322786.10157277&TYPENAME=TestLayer
While the same direct call works:
http://sg.geodatenzentrum.de/wfs_info?SRSNAME=EPSG:3857&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&BBOX=791880.72463009,6321925.37255709,792929.63787777,6322786.10157277&TYPENAME=info:dop
(funny, epsg 3857 is not in the capabilities but works anyhow)
I hope you can find out what is going wrong. Thanks so much for
looking into this!

Hi,
Have you already tried to use WFS connection instead of OGR connection?

Dear all,
I apologize for finding and posting bits and pieces not all at one time.
I fired up 'CONFIG "CPL_DEBUG" "ON"' and there I see, that
"""
HTTP:
Fetch(http://url-to-external-server?SERVICE=WFS&VERSION=1.1.0&MAXFEATURES=1000&REQUEST=GetFeature&TYPENAME=dop
<http://url-to-external-server?SERVICE=WFS&VERSION=1.1.0&MAXFEATURES=1000&REQUEST=GetFeature&TYPENAME=dop>)
"""
So there is no BBOX. On other layers I see
"""
GDALOpen(/vsicurl_streaming/https:...
"""
with BBOX.
No wonder I do not get reliable results if the server is calling some
1000 whatsoever result objects and starts filtering the bbox after.
Any idea what is happening? Or is this something for a GDAL thread?
Best
Lars
