pre_http_request │ filter-hook │ WP 2.9.0

Filters the preemptive return value of an HTTP request.

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:

• An array containing 'headers', 'body', 'response', 'cookies', and 'filename' elements
• A WP_Error instance
• boolean false to avoid short-circuiting the response

Returning any other value may result in unexpected behavior.

Usage

add_filter( 'pre_http_request', 'wp_kama_pre_http_request_filter', 10, 3 );
