WatchGuard HTTP proxy Tiscali page continuously refresh


WatchGuard HTTP proxy causes a continuous page refresh while accessing Tiscali Webmail.

To fix this problem is necessary to edit the HTTP proxy Header configuration of the WatchGuard firewall and add a new rule.



Open the HTTP proxy configuration, go to HTTP Response > Header Fields and add the rule:

cp-widget-boundary:*    Allow


Once the rule has been set, save the configuration to the device.

Accessing the Tiscali Webmail again, the problem is solved.


HTTP-proxy configuration sometime requires lot of time to be tuned but it’s the price for having a better security.
