proxy a web feed

What we want to do is a have squid cache that listens to port 80 and
then store the data in the proxy. This server can not make requests for
further data.

What we need to know is how can we cache this web traffic? We can
re-direct all web traffic to a proxy, but would that work?

PS We can not set get the clients to point there browsers to our proxy.
