			<description>
				Connect to a host. This needs to be done before any requests are sent.
				The host should not have http:// prepended but will strip the protocol identifier if provided.
				verify_host will check the SSL identity of the host if set to true.

			<description>
				Sends a request to the connected host. The url is what is normally behind the hostname, i.e. in [code]http://somehost.com/index.php[/code], url would be "index.php".
				Headers are HTTP request headers.
				To create a POST request with query strings to push to the server, do:
				[codeblock]
				var fields = {"username" : "user", "password" : "pass"}
				var queryString = httpClient.query_string_from_dict(fields)
				var headers = ["Content-Type: application/x-www-form-urlencoded", "Content-Length: " + str(queryString.length())]
				var result = httpClient.request(httpClient.METHOD_POST, "index.php", headers, queryString)
				[/codeblock]
