				Creates request on the underlying [HTTPClient]. If there is no configuration errors, it tries to connect using [method HTTPClient.connect_to_host] and passes parameters onto [method HTTPClient.request].
				Returns [constant @GlobalScope.OK] if request is successfully created. (Does not imply that the server has responded), [constant @GlobalScope.ERR_UNCONFIGURED] if not in the tree, [constant @GlobalScope.ERR_BUSY] if still processing previous request, [constant @GlobalScope.ERR_INVALID_PARAMETER] if given string is not a valid URL format, or [constant @GlobalScope.ERR_CANT_CONNECT] if not using thread and the [HTTPClient] cannot connect to host.
