Irule for URI redirection working for first session

Hi all ,

I have write irule to forward the traffic based on uri , but when I test it I found that there every session is create two times one flow the irule and second flow the default , here my irule

    when CLIENT_ACCEPTED {
set vip [IP::local_addr]:[TCP::local_port]

}

when HTTP_REQUEST {
     if  { [HTTP::uri] contains "/abc" } {
     log local0. "[IP::client_addr]:[TCP::client_port] [IP::local_addr]:[TCP::local_port]"
        pool POOL_1
    }
    else { 
        pool POOL_2
     log local0. "NOT matched , default POOL [IP::client_addr]:[TCP::client_port] [IP::local_addr]:[TCP::local_port]"

    }
}


when SERVER_CONNECTED {
    log local0. "Connection from [IP::client_addr]:[TCP::client_port] to VIP $vip To Node [IP::server_addr]:[TCP::server_port] established."
}

and here the logs

     1.1.1.1%10:65437 10.10.10.10%10:5291
