The scope of this project is a program that will receive a list of proxy servers which will include: Proxy IP/Address:Port,ProxyType (1 for HTTP Proxy, 2 for Socks4 proxy, 3 for Socks5 Proxy 4-For socks proxy with unknown version. The program would be able to run 1-50 threads (Based on settings) and test the proxies in the list. Test procedure would work as follows: 1. Test the proxy against a url we'll provide you which will let you know if the proxy is working and annonymous. If not - mark as failed proxy If yes go to 2: 2. Test the proxy against 4 provided URLs and display failed/work results, and response time. 3. Display all results on a gridview. 4. Save results to a text file. Please note: The program have to connect with the appropriate proxy type to test it. If the proxy is socks and we are not sure if it's socks 4 or 5, on step 1, program will try to connect on step 1 with socks4, if failed socks5. If both failed it will mark the proxy is failed. If yes, continue to step 2 with the type of proxy that works. If you are interested,please include in your response that you are not a b0t.
