I'm looking for an (easy) way to have a http/s proxy server configured to proxy all traffic directed at the internet (speak not at a host in our subnet) to another proxy server.
A short explanation of our setup:
In our lab network all hosts use a proxy server (Squid) for any internet access, now there is an additional network within our lab environment that is almost totally isolated but we would like to allow it's hosts http/s (and maybe ftp) access to the internet. It is a requirement that this access is also done via a proxy server.
I can't give this second proxy direct internet access so the traffic will have to be redirected via the existing proxy server. I do have full control over both servers though and some liberty to make changes.
Any ideas on if or how this is feasible?
