fixed HTTP page automatically when the # connections for the node is reached

Keith,

You cannot nest events in iRules: LB_FAILED cannot reside inside of HTTP_REQUEST. Your iRule will probably look something like this:

when HTTP_REQUEST {  
     HTTP::header insert "X_CLIENT_IP" [IP::client_addr]  
     HTTP::header insert "X-Forwarded-For" [IP::client_addr]  
  
     if { [string tolower [HTTP::uri]] contains "pmcserver" } {  
         pool pm3_qa_pmcserver  
     } elseif { [string tolower [HTTP::uri]] starts_with "/partner" } {  
         pool pm3_qa_soap 
     } else {  
         pool pm3_qa_web 
     }  
 } 
 when LB_FAILED {  
     HTTP::redirect "http://mysite.com/over-limit.html"  
 }

The LB_FAILED event will be triggered the instant that a new connection attempt is made to a pool whose connection limit has already been reached. There are a number of different circumstances that trigger LB_FAILED event and they all have different criteria for load balancing failure. Hope that helps,
