broken-link-checker does not honor proxy setting when snoopy is used

The wordpress options WP_PROXY_HOST and WP_PROXY_PORT are ignored when requests are made with snoopy from wp-content/plugins/broken-link-checker/modules/checkers/http.php. This causes the plugin to hang for a long time as all outgoing http requests on our servers have to be sent through a proxy server for security reasons.

Adding the following code in blcSnoopyHttp#check fixed the problem for me.

$snoopy = new Snoopy;
if (defined(‘WP_PROXY_HOST’)) {
$snoopy->proxy_host = WP_PROXY_HOST;
}
if (defined(‘WP_PROXY_PORT’)) {
$snoopy->proxy_port = WP_PROXY_PORT;
}
