# openUrl method

Future<HttpClientRequest> openUrl (String method, Uri url)

Opens a HTTP connection.

The HTTP method is specified in `method` and the URL to use in `url`.

The `Host` header for the request will be set to the value Uri.host:Uri.port from `url` (if `url.host` is an IP address, it will still be used in the `Host` header). This can be overridden through the HttpClientRequest interface before the request is sent.

For additional information on the sequence of events during an HTTP transaction, and the objects returned by the futures, see the overall documentation for the class HttpClient.

## Implementation
