Chapter 17: Web Hosting Configuration Guide
Web Hosting with Multiple Virtual Groups and Multiple Destination Servers
In the following example, three different servers are used to provide different services for
a site.
The network shown above can be created with the following load-balance commands:
If no application verification options are specified, the SSR will do a simple TCP
handshake to check that the application is “up.” Some applications require specific
commands for proper closure of the connection. The following command shows an
example of how to send a specific string to close a connection on a server:
