2.8. Powerful caching proxy integration
The CacheFu add-on product now ships with Plone. CacheFu can increase the speed of your Plone site 10× to 40× (depending on setup) and makes caching transparent to the end-user.
The important part is that CacheFu allows Plone to explicitly invalidate old caches, so your content is always fresh, even if you have an aggressive caching policy.
It supports several different caching proxies, the most capable and recommended ones being Varnish and Squid — but also works with Apache and IIS to improve caching on these web servers.
