Proxy configuration is an essential part of setting up a secure computing environment. A proxy server acts as a security barrier, making it impossible for an outsider to access your intranet, while allowing your intranet users to access the Internet. The Proxies tab controls the addresses and port numbers that Java Plug-in uses when communicating through a proxy server.
You can set the following proxy configurations from the Proxies tab:
Use browser settings -- Uses Navigator's default proxy settings. Netscape Navigator stores proxy information in a file on the local machine. Java Plug-in reads this file to obtain the proxy information at startup. The default setting is selected.
Proxy Settings -- Overrides Navigator's default proxy settings. Enter the Proxy Address and Port for the protocols you want to use.
Same proxy server for all protocols -- If you are using the same address and port for all protocols, enter the Proxy Address and Port once and select this check box.
