Perhaps that's somewhere we can look at.

I have a system in my companies intranet product which does POST 
submissions automatically though xmlHTTP

Some cobbled together code looks like this:

// ----------------------------------------------------------
var oHTTPHandler = new ActiveXObject("Microsoft.XMLHTTP");

sURL = spSygnLoginURL + "?sessionid=" + sSessionID + "&AuthLogonUser=" + 
sUsername + "&AuthLogonPWD=" + sPassword + "&trig_1=Logon";

oHTTPHandler.open ("POST", sURL, true);
oHTTPHandler.onreadystatechange=fGetMenuFrame;
oHTTPHandler.send(null);
// -----------------------------------------------------------

... which works for my purposes.  I'd like to point out though, that is 
is by far not my most comfortable area of JavaScript, so although that 
works for me there might be dozens of better ways to do it.

Does seem to do POST though.
