– Parses response body at server signatures:
Squid Mikrotik Tinyproxy Litespeed Varnish Haproxy Options: Retries
– Will retry to check the proxy multiple times, for each protocol separately. Keep in mind, it increases proxy checking time.
Max retries:
10 Judges If judge URL starts with “” will be used for HTTPS requests, with “” 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).

Proxy Checker – Proxifier
Proxy Checker
Proxy Checker tool is integrated into Proxifier, but it can be useful on its own. It allows you to test proxy servers and check whether they can work with Proxifier or not.
With Proxy Checker you can:
Test SOCKS v4(A), SOCKS v5, HTTPS and HTTP proxy servers.
Get an easy-to-understand report with recommendations that can help to solve a problem (if any).
Measure proxy server response time (latency).
To check a proxy with Proxy Checker, click the Check button in Proxy Settings dialog. Alternatively you can run Proxy Checker manually in Proxifier with the toolbar button, View->Proxy Checker… or Start->Programs->Proxifier->Proxy Checker (Windows Start menu) and specify proxy details with the Proxy Server… button.
Use the Start Testing button to begin the test.
To adjust Proxy Checker settings click the Test Settings… button.
The following options are available:
Work through Proxifier — Proxy Checker will bypass Proxifier when this option is disabled. This is the default value and it should only be changed in a very special scenario (e. g. the target proxy is not directly accessible).
Target host and Port — set the target host for the test connection.
Load a default web page from the host — enable to test data transfer.
You can enable/disable particular tests.
You may use and distribute Proxy Checker as a standalone application (). Proxy Checker is free for personal and noncommercial use.
