 Responses are always asynchronous, so that the call to the method returns
 immediately instead of waiting to receive the response::
 Symfony's HTTP client is asynchronous by default. When you call ``request()``,
 the HTTP request starts immediately, but the method returns without waiting for
 a response. Your code only blocks when you actually need the response data::

    //code execution continues immediately; it doesn't wait to receive the response
    //the request starts, but execution continues without waiting
    $response = $client->request('GET', 'http://releases.ubuntu.com/18.04.2/ubuntu-18.04.2-desktop-amd64.iso');

    //gettingthe response headerswaits until they arrive
    //this blocks untilthe response headersare received
    $contentType = $response->getHeaders()['content-type'][0];

    // trying to get the response content will block the execution until
    // the full response content is received
    // this blocks until the full response body is received
    $content = $response->getContent();

 This component also supports :ref:`streaming responses <http-client-streaming-responses>`
 for full asynchronous applications.
 The HTTP client also supports :ref:`concurrent requests <http-client-concurrent-requests>`
 to make multiple HTTP requests in parallel, and :ref:`streaming responses <http-client-streaming-responses>`
 to process response data in chunks for fully asynchronous applications.
