Filters the preemptive return value of an HTTP request.
Description
Returning a non-false value from the filter will short-circuit the HTTP request and return early with that value. A filter should return one of: <ul> <li>An array containing 'headers', 'body', 'response', 'cookies', and 'filename' elements</li> <li>A WP_Error instance</li> <li>Boolean false to avoid short-circuiting the response</li> </ul> Returning any other value may result in unexpected behavior.
Parameters
$responsefalse|array|WP_Error
A preemptive return value of an HTTP request. Default false.
