Web Cache

You can use web caching to cache web pages from any web server. All traffic between a client network and one or more web servers is then intercepted by a web cache policy. This policy causes the FortiProxy unit to cache pages from the web servers on the FortiProxy unit and makes the cached pages available to users on the client network. Web caching can be configured for standard and reverse web caching.

In a standard web caching configuration, the FortiProxy unit caches pages for users on a client network. A router sends HTTP traffic to be cached to the FortiProxy unit.

You can also create a reverse proxy web caching configuration where the FortiProxy unit is dedicated to providing web caching for a single web server or server farm. In this second configuration, one or more FortiProxy units can be installed between the server network, and the WAN or Internet or traffic to be cached can be routed to the FortiProxy units.
