I need to set up a HTTP proxy server (call it server
A) for users to access Internet. For some reason, it needs to forward all the requests to another HTTP proxy server (call it server
C is not directly accessible by
A, unless by using another HTTP proxy server
User --> A --> B --> C
C is controlled by me and I can install anything or configure anything on them. But
B is a existing HTTP transparent proxy which I cannot control or configure.
I don't know which software can support this kind of "proxy chaining forwarding".
privoxy or other software support this? Thanks.
