Question:
HTTP POST request gets transformed to GET request

Description:
How exactly does the WireCloud proxy work? We use the following code for a request via the WireCloud proxy:

MashupPlatform.http.makeRequest(url, {
method: 'POST',
forceProxy: true,
onSuccess: function (response)

,
onFailure: function (response)

,
onComplete: function ()

});

The browser network analysis shows that a POST request gets send to https://example.com/cdp/https/rest.example.com/path/to/service. Our webservice that gets called by the url however logs, that it receives a GET request.

The access log of our rest service hosted by a tomcat shows:

192.168.60.221 - - [26/May/2016:10:38:31 +0200] "GET /path/to/service HTTP/1.1" 405 1013
192.168.60.221 - - [26/May/2016:10:38:42 +0200] "POST /path/to/service HTTP/1.1" 204 -

The first call is done with the MashupPlatform.http.makeRequest call listed above, the second call is done with jQuery like this:

$.ajax(

);

This works perfeclty fine when we set the CORS header in our webservice.

So what may be the reason, that WireClouds proxy does not work as expected?
