Cannot set Content-Type of Sherlock HTTP POST requests

Subject: Cannot set Content-Type of Sherlock HTTP POST requests

This is RadarWeb Bug #3136237.

Using the sample code snipped provided in http://developer.apple.com/techpubs/macosx/AdditionalTechnologies/ Sherlock/Tasks/CreatingWebServices.html , it's impossible to set the HTTP POST request's Content-Type header properly.

The following code, when executed from Sherlock's XQuery channel, demonstrates the problem:

let $cgi := "http://localhost/cgi-bin/printenv.cgi";

let $quote := dictionary(("ticker", "AAPL"), ("price", 123.45))

let $query :=
<quote>
<ticker market="NASDAQ"> { $quote/ticker } </ticker>
<price currency="USD"> { $quote/price } </price>
</quote>

let $headers := dictionary (
            ("Content-Type",  "text/xml; charset=utf-8"),
            ("SOAPAction", "urn:offer-quote")
        )

let $html := http-post($cgi, $query, $headers)/DATA

return $html


(No, $query is not a valid SOAP call, but that's not the point here.)

Here's what the CGI sees as the HTTP headers:

CONTENT_LENGTH  '92'
CONTENT_TYPE    'application/x-www-form-urlencoded'
HTTP_SOAPACTION 'urn:offer-quote'

Changing the Content-Type to:

            ("Content-Type:",  "text/xml; charset=utf-8")

produces:

CONTENT_TYPE ': text/xml; charset=utf-8, application/x-www-form-urlencoded'

Finally,

            ("Content-Type: text/xml; charset=utf-8;",  "")

yields

CONTENT_TYPE 'text/xml; charset=utf-8;:, application/x-www-form-urlencoded'

There should be a way to have Sherlock (via WebFoundation) to use a specified HTTP Content-Type for a HTTP POST request, without having "application/x-www-form-urlencoded" or ":" appended to the header.
