[line 77]
Class representing a HTTP response

The class is designed to be used in "streaming" scenario, building the response as it is being received:

 $statusLine = read_status_line();

 $response = new HTTP_Request2_Response($statusLine);
 do {
     $headerLine = read_header_line();
     $response->parseHeaderLine($headerLine);
 } while ($headerLine != '');
 
 while ($chunk = read_body()) {
     $response->appendBody($chunk);
 }
 
 var_dump($response->getHeader(), $response->getCookies(), $response->getBody());
