Access the Server Manager, and click the Routing tab.
Click the Set Routing Preferences link.
The Set Routing Preferences page is displayed.
Select the resource from the drop-down list or click the Regular Expression button, type a regular expression, and click OK.
Select the Route Through option.
Select the checkboxes for proxy array or parent array.
You can only enable proxy array routing if the proxy server you are configuring is a member of a proxy array. You can only enable parent routing if a parent array exists. Both routing options are independent of each other.
If you choose to route through a proxy array and you want to redirect requests to another URL, select the redirect checkbox.
Redirecting means that if a member of a proxy array receives a request that it should not service, it tells the client which proxy to contact for that request.
Click OK.
Click Restart Required.
The Apply Changes page is displayed.
Click the Restart Proxy Server button to apply the changes.
