X-Cnection: close vs Connection: close
I'm having difficulty understanding the difference between these two. Article SOL6997 states:
"The X-Cnection: close header is also added to server-side connections utilizing an existing Keep-Alive connection if the client request included the Connection: close header. The BIG-IP uses the X-Cnection: close header to track client-side connections that want to close the connection after receiving a response through a virtual server utilizing the OneConnect feature."
Is the "X-Cnection: Close" header NOT an industry standard thing and just a technique that the LTM uses in place of the original/correct "Connection: closed" header? If so, does the origin webserver just ignore this field since it doesn't recognize the "X-Cnection: Close" header?
