A server-based script that will download lists of anonymous proxy servers once a day. These proxy servers would then be tested for anonymity and validity. Proxies that are not working, or are not anonymous, would be removed. The working proxies would be written to a MySQL database on our server.
We do not have a list of proxy list sources, so you would need to provide this.
Our objective is to have a fresh list of 5,000-10,000 anonymous proxy servers each day.
