How to close client connection when server closed connection

I am developing a upload service,And I use the f5 Load balance. The upload server will check the upload is correct. If server find some error in upload stream, Server should close the connection.

 

 

I can close the underlying socket between the server and f5. But I cannot close the connection between f5 and client.

 

I tried to use the irule like

 

SERVER_CLOSED

 

{

 

clientside

 

{ reject }

 

}

 

but no effect.

 

 

 

How can i do this?

 

 

 

 

 

 

Very thanks!

    Hi coolzyt,

    Try this and see if it works for you: 

     
when HTTP_REQUEST {
log local0. "Client IP Address:  [IP::client_addr]."
}
when LB_SELECTED {
log local0. "Load Balanced Server:  [LB::server addr]"
}
when SERVER_CLOSED {
log local0. "Server Connection Closed to [IP::server_addr]."
TCP::close
log local0. "TCP Connection Closed to [IP::client_addr]."
}

    Thank you Michael!

     

    I have solved it. The server must use the RST packet to closed the connection,And f5 can close client connection now!

     

    The only confused thing is the RST won't trigger SERVER_CLOSED event.Anyway, It works!
