If you have a Cisco Local Director configured with ColdFusion you can restrict all incoming site traffic. Restricting traffic is helpful when you want to place a Web site in maintenance mode. To restrict Cisco's Local Director from submitting traffic to a Web server, follow these steps:
Open the Server Configuration page in the ColdFusion Administrator (by clicking Tools>Web Servers in the navigation frame).
In the Server Configuration page, locate the name of the Web server, then do one of the following:
clear the Enabled checkbox. When you clear the Enabled checkbox, the local director box will be notified to stop sending traffic to the Web Server. You can disable the traffic restriction at any time by checking the Enabled checkbox.
or
check the Restrict check box. When you check the Restrict check box, the DFP protocol coming from the load balancing box will be ignored and the ColdFusion Server will report the Web Server is busy. The Cisco Local Director will continue to process requests but will redirect the traffic elsewhere. All existing connections will continue to be serviced by the Web Server but all new connections will be redirected elsewhere. You can disable the traffic restriction at any time by clearing the Restrict checkbox.
Notes:
The difference between the Enable and Restrict controls is that when enabled is not set, the Local Director is not notified of server capabilities.
Disabling these checkboxes will not remove the configuration of the load balancing hardware from ColdFusion.
Tip:
You can also configure a ColdFusion probe to restrict Web Server traffic.
