RE: [squid-users] Re: Encrypted traffic with proxy server?

We've set up a reverse proxy with the --enable-ssl option. Our back end
webservers are http on port 80. Squid only accepts traffic from port 443.
The browsers are connecting to the proxy (run in accelerator/reverse proxy
mode) All traffic between internet users and the proxy are ssl. From the
proxy to our web servers are not ssl.

A proxy is not the same as a reverse proxy, although it is close. One
solution would be to have 2 squid boxes in a server room, where the only
sniffing that could be done would have to be done within the server room.
Configure one has a reverse proxy, sending all traffic to the normal proxy.

Student PC --> ssl connection--> squid as reverse proxy in server room -->
port 80 -->squid as proxy in server room --> internet webservers

Squid supports encrypted connections to clients (use the --enable-ssl
configure option), but to date no known browser supports encrypted
connections to proxy servers.

You could use something like Stunnel (www.stunnel.org) on the client to
connect to the proxy, then have the browser use 127.0.0.1 as the proxy
server.

This is just a suggestion - I have not tried this exact setup, so I can't
say for sure if it will work.
