FAQs
| Q: Why would I need to adjust my firewall exceptions? |
A: A Firewall does an acceptable job of protecting your computer against many backdoor communication attempts. Many applications that require a firewall exception to be added will do so automatically during installation; however, sometimes you will have to manually allow an application to have access to the internet.
| Q: What is caching? |
A: Caching is the technique of storing frequently visited information in a location close to the requester. A Web cache stores Web pages and content on a storage device that is physically or logically closer to the user, which is closer and faster than a Web lookup. By reducing the amount of traffic on overburdened Web servers, caching provides significant benefits to ISPs, enterprise networks, and end users. Our site is dynamic and to maximize its use, we strongly recommend that it is excluded from any existing caching device.
