    Please Note:

    1. The Http and Security proxies are only required if you are trying to connect to a website which uses a non-standard port (i.e. other than port 80). If you use the proxy for standard surfing, it may slow down your internet connection. We recommend disabling the proxy when you do not need it.
    2. The purpose of the proxy is to allow access to http/ftp ports, that might otherwise be blocked by the firewall.
    3. The proxy is for the main dept networks. labs outside the main networks don't need the proxy services (lmc, ecsl, security, etc).
    4. Once you setup your proxy settings, you can disable using the proxy by selecting the Direct connection to the internet (for Netscape) or deselecting Use a proxy server (for Internet Explorer). Usually this will not clear your proxy settings when you re-enable the proxy.
