Azure proxy – admin-ajax.php loads at original site_url

  • So, we’re having to load our wordpress (multi-site) two ways. If people are on the intranet they load it at its regular URL. If they’re coming through externally they’re using an Azure proxy.

    I added this to wp-config.php and it works for everything except ajax calls, which keep getting called over the site_url which is the database (internal url, not proxified) for proxy users.

    /** Sets up WordPress vars and included files. */
if (isset($_SERVER['HTTP_X_MS_PROXY']) && ($_SERVER['HTTP_X_MS_PROXY'] == 'AzureAD-Application-Proxy')) {
$host = 'ourwebsite-external.msappproxy.net'; }
else {
$host = $_SERVER['HTTP_HOST']; }

//$host = $_SERVER['HTTP_HOST'];
$protocol = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off') || (isset($_SERVER['SERVER_PORT']) && $_SERVER['SERVER_PORT']===443)) ? 'https://' : 'https://';
define('WP_SITEURL', $protocol . $host);
define('WP_HOME', $protocol . $host);
require_once(ABSPATH . 'wp-settings.php');

    How can I get the site to set the ajaxurl so that it uses the proxy address for external users and the regular site address for our intranet users?

    ajaxurl is typically constructed by concatenating “/admin-ajax.php” to the return from admin_url(), which apparently returns your internal URL. The return value is filtered with “ajax_url”. Maybe you can conditionally set the proper URL based on $_SERVER[‘HTTP_X_MS_PROXY’] existence and value?

    It’s possible your theme or plugins arrive at ajaxurl value through different means, so the filter solution may fail to cover all situations. It’s a good place to start at least.
