This way, the server for the new Web page knows the last Web page that you viewed. For example, if you are on www.symantec.com and click www.microsoft.com, the browser sends www.microsoft.com the information that you are currently viewing www.symantec.com. If you block referer information, the server of the page you are requesting to see does not know what page you saw last. By default, Norton Internet Security (NIS) and Norton Personal Firewall (NPF) blocks this information. However, some Web pages require this information before allowing you to view the page. If you need to allow referer information to pass to a particular Web page, you must create a rule for it.To create a rule:1. Open NIS or NPF.2. Click Options.3. Click Internet Security or Personal Firewall. This step is not always needed.4. Click the Web Content tab.5. Click Add Site. A new site/domain box appears.
