Use async with drupal_http_request()

Question

I need to make an asynchronous call with drupal_http_request(). Is it possible?

Answer 1

With drupal_http_request this is not possible. But you can have a look at the module HTTP Parallel Request & Threading Library which allows you to do non-blocking requests.

From the module page:

Using stream_select() it will send http requests out in parallel. These requests can be made in a blocking or non-blocking way. Blocking will wait for the http response; Non-Blocking will close the connection not waiting for the response back. The API for httprl is similar to the Drupal 7 version of drupal_http_request().
