This function’s access is marked private. This means it is not intended for use by plugin or theme developers, only in other core functions. It is listed here for completeness. Use WP_Http::request() instead.

Dispatches a HTTP request to a supporting transport.


Tests each transport in order to find a transport which matches the request arguments. Also caches the transport instance to be used later.

The order for requests is cURL, and then PHP Streams.
