Judges

If judge URL starts with "https://" will be used for HTTPS requests, with "http://" for HTTP.

SOCKS4 and SOCKS5 will use all proxy judges.

Validate Field:
If not empty - Enable response validation by text which you type. Response will be valid is this string was found in response body. Also support Regexes (Regex builds through Javascript RegExp).

Options:

Swap - Enable swap the judge url after each request, to minimize servers busy. Will split requests across all active proxy judges. If disabled - will use only one proxy judge with minimum response timeout.

Add new:

Url - Must be an unique.

Ip

Your ip address will be cached before start the first check. If you are changed ip address, press the check button for re-lookup and re-cache your new ip.
