simple irule for redirection

You can use HTTP::uri to view or modify the URI before the request is sent to the node.

Here is one example:

when HTTP_REQUEST {
   if { [HTTP::uri] equals "/" }{
      HTTP::uri "/app/index.html"
   }
}

This rule with trigger when a client makes an HTTP request. If the client requested the root document (/), the rule would rewrite the URI of the request to /app/index.html. The VIP's load balancing algorithm would handle the node selection so you don't have to worry about it within your rule.

If you want more info on the HTTP::uri options try checking the wiki (Click here)or search the forum for URI rewrite.
