Rhino, a good friend of mine, released a new version of his fantastic proxy checking tool Charon today. Here is a little explanation about Charon if you don't know what it´s about:
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
Charon, despite it having not been updated for a few years, is still working fine as of today (May 2012). You can still load a list of proxy servers into the program, and check them for various characteristics, including whether they spill the IP address or are anonymous.
Depending on your setup, you may need configure the program to use a different proxy judge script, which you may still find on the Internet these days.
Once that is out of the way, you can have the program scan your list of proxies in record time, and even download or find new proxies for you for use in the software program. As for as proxy checkers go, I'd say it is still one of the best out there, provided that you set it up properly.
First thing that you should do is test the judges in the Judge options to find the ones that are still working. Activate the judges that are reported to be still working, and remove the judge that is listed as bad or not working.
