WFS POST requests: "No template provided" error

[Frank Steggink]

Hello Yewondwossen,

Sorry, no improvement here. I'm not getting an error, but I got a time
out, while posting (DescribeFeatureType) to the original server URL
(http://map.ns.ec.gc.ca/MapServer/mapserv.exe?map=/mapserver/services/en
vdat/config.map).
Also, the other service I mentioned,
http://www.bsc-eoc.org/cgi-bin/bsc_ows.asp, uses this same URL as online
resources, which already gave the template error.

I'm a bit out of options right now. As already mentioned, when I'm using
GET, then everything works fine, so our client will be able to access
MapServer. I'll try a few other MapServer WFS's, and see what they do.
(Using POST, and the online resource URL's.) There are quite a lot of
them online. If they all give the same result, then I'm going to file a
bug in Trac. It is no coincidence if several servers, which are set up
independently, all have the same problem.

Frank

Hi There,

  WFS POST is supported by MapServer. Looking into this thread, you
mentioned a couple of URLS and I have tried the follwing one : 
"http://map.ns.ec.gc.ca/MapServer/mapserv.exe?map=/mapserver/services/en
vdat/config.map"

  I have tried WFS post requests  describefeature and getfeature  with
this service and It responds correctly. It is a Mapserve 4.8.3.

  I am guessing that there is something 'wrong" with the service
accessed though the script at http://map.ns.ec.gc.ca/envdat/map.aspx
where the post requests are not maybe transfered properly to Mapserver.

  Hopefully this helps.

Best Regards,
