I want to make a simple proxy checker in e.g., Perl. It doesn't have to be too flashy, but it will need to check a lot of proxies and at least tell me their speed and if they are anonymous or not. At the moment I check 1000s of proxies in Charon, but I want something that integrates better with my existing perl and bash scripts. My main problem with the other checker scripts I can find on Google is that they only seem designed for testing smaller lists of about 30 proxies. And they only check against one site to test for anonymity e.g., whatismyip.com. Now, as my script will run with multiple threads, I don't want to just bomb one site with 1000s upon 1000s of requests; surely this wouldn't go down too well? I see that many of the popular proxy checker tools use php scripts called judges. Can these judge hosts handle all these requests e.g., samair.ru? Or do they set limits? Perhaps I could host my own? Also, what criteria do I use to check if a proxy is "Google Passed"? Is it equivalent to any proxy where Google can't tell it is actually a proxy e.g., elite proxy? Or is it any proxy not in Google's blacklist? How would I make the test? Thanks for reading.
