To enable web caching for the explicit web proxy
You can enable web caching for the explicit web proxy on FortiGate units that support
WAN optimization and web caching.
1 Use the procedure "To enable the explicit web proxy on one or more interfaces" on
page 211 to enable the explicit web proxy
2 Go to WAN Opt. & Cache > Cache and select Enable Cache Explicit Proxy.
3 Select Apply to save your changes.
Web content requested by users using the explicit proxy are now cached by the
FortiGate unit using the WAN optimization web cache.
Using the FortiOS 4.0 customizeable GUI feature you can add a WCCP widget to the
web-based manager and use this widget to add WCCP entries to the FortiGate
configuration.
Configure settings for Web Cache Communication Protocol (WCCP) version 2 to optimize
web traffic, thus reducing transmission costs and downloading time.
When a web client (on a computer) makes a request for web content, WCCP allows the
routers on the local network to redirect the web content requests to the appropriate web
cache server on the local network. If the web cache server contains the information in the
web content request, the web cache server sends the content directly to the local client. If
the web cache does not contain the requested information, the web cache server will
download the HTTP information, cache it, and send it to the local client. The local client is
not aware this caching is taking place.
For web caching to function, local network traffic must be directed through one or more
routers that are able to forward the HTTP requests to the web cache servers. The
FortiGate unit can act as a WCCP version 2 enabled router and direct web content
requests to configured web cache servers.
The web caching will speed up downloads by not accessing remote websites for each
HTTP request. It will also reduce the amount of data a company network sends and
receives over the Internet, reducing costs.
To configure WCCP from the web-based manager, go to System > Admin > Admin Profile
and create a custom menu layout in your administrative profile and add the WCCP page. It
is in the Additional content category. See "Configuring an admin profile" on page
