[Qgis-user] Re: QGIS WPS Plugin 0.75 fails to execute while 0.6.16 worked

[Yingqi Tang]

Hi Horst,

I think I find out the difference. After the upgrade (to 0.74/0.75), when
WPS plugin sends <Execute> request with xml in the data payload, it sets
the HTTP POST request content-type header to be "
application/x-www-form-urlencoded", which is incorrect for HTTP POST
request with xml payload (see http://en.wikipedia.org/wiki/POST_(HTTP)).
The consequence is that some web server (e.g. Tomcat) may cut off the
actual data payload when request pass through.

I understand that may be a behavior of core QGIS library, but do you think
it's something you can control in your code? Or does it make sense to you?

Thanks.
Yingqi
