Irule to read cookie value of amlbcookie

Minor syntax correction:

when HTTP_REQUEST { 
    if { [HTTP::cookie exists amlbcookie] } { 
        log local0. [HTTP::cookie value amlbcookie] 
        switch [HTTP::cookie value amlbcookie] { 
            "01" { 
                node 10.29.35.111 80
                log local0. "matched 01" 
            } 
            "03" {
                node 10.29.35.112 80
                log local0. "matched 03" 
            }
        } 
    } else { 
        pool Auth_SSL_Offload 
        log local0. "default" 
    } 
}

You need to specify the port when issuing a node command.
