Adding additional headers should be trivial, like here:

HTTPSocket
	httpGetDocument: 'http://www.google.com'
	args: 'q=squeak'
	accept: '*'
	request: 'X-My-Header: foobar', String crlf,
                  'X-Your-Header: anotherone'.

The #request: argument takes an arbitrary string that's added to the 
request header[*]. Ditto for #httpPost:content:type:accept:request:.

[*] Yes, the argument is badly named. It should be called #headers:.
