Actually i need to know whether this module can do the following:
I have an url to call with POST
e.g http://example.com/ws/myws.ws
Depending on the parameters passed through POST, i need to return a result in either xml or json format.
Does this module allow this type of operation ?
I tried to use the recommended release 7.x-1.0, its giving out some errors on the forms of the module and there is nothing indicating how to choose the response format.

According to the description of WSClient, WSclient seems to do what i want.
