Prestwood IT Load Balancer: LB: Routing Options By Mike Prestwood

Routing Options

Load Balancer $99.95 Load Balancer Developer* $995 *includes Delphi 6 source code

The entries in the form's grid are segregated by the three sections in the routing table:

• Machine: The precursor to the domain in the HTTP request. The default would be "www".
   
• Document: The page to fetch off of the specified domain. For example, "www.prestwood.com/admin".
   
• Destination: The actual destination address to route the indicated HTTP request to. Note that this destination can be more than one address for the same request. For example, look at the following entries:
  
  /news-today http:127.0.0.44:82
  /news-today http:127.0.0.46:80
  
  This routing table indicates that HTTP requests to the "news-today" page off of the bound I.P. address will be routed to either destination address. If the Load Balancer detects too many outstanding requests at the first address, and fewer requests to the second address, it will redirect the HTTP requests to the second address until the load on these two sites is balanced.
