Chapter 16 SSL VPN for FortiOS 5.0 : Basic Configuration : Additional configuration options : Configuring cache cleaning
  
Configuring cache cleaning
When the SSL VPN session ends, the client browser cache may retain some information. To enhance security, cache cleaning clears this information just before the SSL VPN session ends.
 
The cache cleaner is effective only if the session terminates normally. The cache is not cleaned if the session ends due to a malfunction, such as a power failure.
To enable cache cleaning
To enable cache cleaning on the full-access portal, you would enter:
config vpn ssl web portal
edit full-access
set cache-cleaner enable
end
Cache cleaning requires a browser plug-in. If the user does not have the plug-in, it is automatically downloaded to the client computer.
