Simple answer - with a caching proxy server.

Longer answer - accelerator mode is incompatible with caching mode - you use
either one, or the other, but not both on the same proxy.

They're not in the least bit interchangeable, either:

 - caching mode is where you're running a service for clients (browsers) to
improve their performance accessing any server/s

 - accelerator mode is where you're running a service for servers (websites)
to improve their performance (maybe load-balancing, maybe high-availability)
for any clients which access them.

Caching mode caches, accelerator mode doesn't.

From the URL you quoted above: "If you wish only to cache the 'rest of the
world' to improve local users browsing performance, then accelerator mode is
irrelevant."

"Sites which own and publish a URL hierarchy use an accelerator to improve
access to it from the Internet. Sites wishing to improve their local users'
access to other sites' URLs use proxy caches."

So, accelerator mode or caching mode - different purposes, it's your choice
which you need.
