Proxy Checkers on the other hand can automate the process so that the proxies can be verified in a fraction of the site that a manual process would take.

The Free Web Proxy Checker has been specifically designed to test so called web proxies. A web proxy usually consists of a form on a website that a user can use to access another website from. This is different from standard proxy servers that need to be added to a program’s proxy settings before they can be used.

The web proxy checker has lots of settings of which most are not needed for basic verifications.

All that is basically needed is to paste a list of web proxy urls into the application’s interface. The program will test the proxies against the Gmail website to see if it is displayed correctly. This can be changed to any other website if necessary.

A click on the Start button will initiate the web proxy scan. Good proxies will be saved in the goodprox.txt file while bad proxies in the badprox.txt file.

Advanced users can tweak many different settings in the program from simultaneous threads over timeouts and retries to whitelist or blacklist specific countries, changing user agents and running a distribution web server.

This is the follow up to the proxy filtering program Calamity. It provides a fully customisable way of filtering out unwanted proxies via control files, a proxy tester to check anonymity – and a fully functional search engine crawler to find lists of posted proxies. Included within the kit is a php checker which can be uploaded to your own webspace to spread the processor load and bandwidth of the actual testing. This is fully integrated into Charon where it will simply send your pages lists of proxies and harvest the results
