So here is the working not working setup. Unfortunately the working
OGR WFS client layers are all private so I can not share them.<br>
<br>
This call delivers objects as expected:<br>
<a class="moz-txt-link-freetext" href="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">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</a><br>
This one, too:<br>
<a class="moz-txt-link-freetext" href="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">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</a><br>
<br>
Data is delivered in the correct srs (verified manually with QGIS).<br>
<br>
This call doesn't work as described before as BBOX is not
transmitted to external server:<br>
<a class="moz-txt-link-freetext" href="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">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</a><br>
<br>
While the same direct call works:<br>
<a class="moz-txt-link-freetext" href="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">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</a><br>
(funny, epsg 3857 is not in the capabilities but works anyhow)<br>
<br>
I hope you can find out what is going wrong. Thanks so much for
looking into this!<br>

No wonder I do not get reliable results if the server is

Any idea what is happening? Or is this something for a
