Ability to block Opera Mini browsers' Turbo mode.
The Opera Mini browser contains a Turbo mode, which makes use of proxy technology to speed up browsing.
Turbo mode enables a proxy within the Opera Mini browser which bypasses your proxy server and so bypasses the Smoothwall web filter. It can operate in HTTP mode or via port 1080.
