Specifying proxy servers
If your computer accesses the Internet by connecting to a network protected by a firewall, you may need to speciify proxy servers to access webpages and other Internet resources. Your browser sends requests for webpages to the proxy server, which then retrieves the page for you.
If you need to specify a proxy server, your network administrator should provide you with the information you need. The information should include the type of proxy server to specify (for example, a web proxy server), the IP address or DNS name for the server, and a port number.
You specify proxy server information using Network preferences. You can open the appropriate Network preferences pane using Safari preferences.
Choose Preferences from the Safari menu and click Advanced, then click Change Settings.
The Network pane of System Preferences opens showing the proxy settings for the type of connection you are using. Select the checkbox for the type of proxy server (for example, Web Proxy). Enter the IP address or DNS name provided by your network administrator in the first text box and the port number in the second box. When you're ready, click Apply Now.
