A Proxy Server lies in between your computer and the Internet. When you visit web content through your computer, you connect to your proxy. The proxy then requests the content you're searching for on your behalf and returns it to you. A proxy is useful for filtering Internet content, connecting to the Internet through firewalls and archiving web pages for quicker retrieval.
TWC Central does not support the use of proxy servers, and recommends that you disable proxies through your browser.
