reverse proxy and web server on *same* machine

I am about to run an open source (PHP) CMS on an Apache/MySQL setup.

I was thinking if it is possible to run a caching proxy on the SAME
server (perhaps Apache or Pound) to cache pages from the site.

Would this speed up the site or should I put it on separate servers?

Thanks.

Thanks for the answer.

The CMS is TYPO3 and it has the ability to use cache-control headers.

So I assume that it can specify some pages as safe to cache. Can I
enable mod_cache (sp?) and one of the storage modules?

Will this speed up the site?

Thanks,
