Socket-based HTTP future, for making HTTP requests using future semantics. This is an alternative to CURLFuture which has better resolution behavior (select()-based wait instead of busy wait) but fewer features. You should prefer this class to CURLFuture unless you need its advanced features (like HTTP/1.1, chunked transfer encoding, gzip, etc.).

Example Usage

$future = new HTTPFuture('http://www.example.com/');
list($response_body, $headers) = $future->resolvex();

Or

$future = new HTTPFuture('http://www.example.com/');
list($http_response_status_object,
     $response_body,
     $headers) = $future->resolve();

Prefer resolvex() to resolve() as the former throws HTTPFutureHTTPResponseStatus on failures, which includes an informative exception message.
