Redirecting Client Requests to an Alternate URL
In the event that a load balancing virtual server of type HTTP or type HTTPS goes DOWN or is disabled, you can redirect requests to an alternate URL by using an HTTP 302 redirect. The alternate URL can provide information about the status of the server.
You can redirect to a page on the local server or a remote server. You can redirect to a relative URL or an absolute URL. If you configure a redirect to a relative URL consisting of a domain name with no path, the NetScaler appliance appends the path of the incoming URL to the domain. If you use an absolute URL, the HTTP redirect is sent to that URL with no modification.
Note: If a load balancing virtual server is configured with both a backup virtual server and a redirect URL, the backup virtual server takes precedence over the redirect URL. A redirect is used only when both the primary and backup virtual servers are DOWN.
To configure a virtual server to redirect the client request to a URL by using the command line interface
At the command prompt, type:
set lb vserver <vServerName> -redirectURL <URLValue>
set lb vserver Vserver-LB-1 -redirectURL http://www.newdomain.com/mysite/maintenance
To configure a virtual server to redirect the client request to a URL by using the configuration utility
- Navigate to Traffic Management > Load Balancing > Virtual Servers, and open the virtual server.
- In Advanced Settings, click Protection, and specify a redirect URL.
