[Laszlo-user] html5 version incorrectly appends to the Content-Type request header (openlaszlo 4.9)

[augusto callejas]

hi-

i have code below that performs a POST request, where i'm setting the 
Content-Type HTTP header.

===
        <dataset name="stopWS" querytype="POST" type="http" 
datafromchild="true" proxied="false" queuerequests="true">
                <method name="doRequest">
                        setHeader('Content-Type', 
'application/x-www-form-urlencoded; charset=UTF-8');
                        super.doRequest();
                </method>
        </dataset>
===

===
                                        stopWS.setAttribute('src', '/api/stop');
                                        stopWS.doRequest();
===

i'm seeing two different values in the HTTP request header Content-Type on the 
server, depending on the version of the client:

swf8: application/x-www-form-urlencoded; charset=UTF-8
html5: application/x-www-form-urlencoded; charset=UTF-8 
application/x-www-form-urlencoded

the html5 version of my app is appending "application/x-www-form-urlencoded" to 
the Content-Type header.
this appears to be a bug, correct?

thanks,
augusto.

ps: i'm running openlaszlo 4.9 in proxied mode.
