I'm using Fiddler to POST data to a webservices endpoint.

URL:

http://localhost/moodle/webservice/rest/server.php?wstoken=011ea2f81ad592033ed197d2a4956d6d&wsfunction=local_wstemplate_hello_world

POST Data:   blah=12345

in /webservice/rest/server.php, line ~35, (before anything really gets executed, I have:

die(var_export($_POST).var_export($_GET));

Which outputs:

array (
)

array (
'wstoken' => '011ea2f81ad592033ed197d2a4956d6d',
'wsfunction' => 'local_wstemplate_hello_world',
)

It is not reading the post data at all.  Is there something I'm missing or a setting I need to turn on?

Edit:

Using the default WStemplate, "Client.php", which creates an XMLRPC request - the script POSTs a variable to modify what the welcome message is.  So instead of "Hello World" -  I can set  $welcomemsg = 'asdfasdfasdf, ';   This data is POSTed to the server.

No matter what I set this parameter to, the output never changes. ($_POST is empty).  The response is always "Hello World, Patrick" (The parameter default).
