# open method

Future<HttpClientRequest> open (String method, String host, int port, String path)

Opens a HTTP connection.

The HTTP method to use is specified in `method`, the server is specified using `host` and `port`, and the path (including a possible query) is specified using `path`. The path may also contain a URI fragment, which will be ignored.

The `Host` header for the request will be set to the value `host`:`port` (if `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

    Future<HttpClientRequest> open(
        String method, String host, int port, String path);
