源代码

File: wp-includes/pluggable.php

function wp_validate_redirect($location, $default = '') {
	$location = trim( $location, " \t\n\r\0\x08\x0B" );
	// browsers will assume 'http' is your protocol, and will obey a redirect to a URL starting with '//'
	if ( substr($location, 0, 2) == '//' )
		$location = 'http:' . $location;

	// In php 5 parse_url may fail if the URL query part contains http://, bug
