ClusterRedirector provides load balancing and fault tolerance by redirecting client requests to an available workgroup of servers.

Parameters

hosts The comma delimited list of the names of the servers in the workgroup that requests will be redirected to.
interval Used to specify in milliseconds how often the workgroup servers status is updated.

A value greater than or equal to 50 milliseconds.

If an interval is not specified or if 0 is used then the workgroup server status is only checked if the method is best when the request is made.

1000 milliseconds is a good value to use.

A value too small may have a negative impact on performance and a value too large when method is best may delay use of a recovered workgroup server.

method The method used to determine which server within the workgroup will service the current request.

best - the server with the best response time.
next - the next available server.

If a method is not specified then next is used.
