Cntlm is an authenticating HTTP proxy. It takes the address of your proxies as a parameter and opens a listening socket, forwarding each request to it (moving on in a circular list if the active parent proxy stops working).

When the chain is set up, cntlm is to be used as the primary proxy in your applications.
