Hi, As far as I see HAProxy removes that header if its contained in the response from the backend (nginx with keepalive enabled) because RC7230 says so:
6.1. Connection The "Connection" header field allows the sender to indicate desired control options for the current connection. In order to avoid confusing downstream recipients, a proxy or gateway MUST remove or replace any received connection options before forwarding the message. When a header field aside from Connection is used to supply control information for or about the current connection, the sender MUST list the corresponding field-name within the Connection header field. A proxy or gateway MUST parse a received Connection header field before a message is forwarded and, for each connection-option in this field, remove any header field(s) from the message with the same name as the connection-option, and then remove the Connection header field itself (or replace it with the intermediary's own connection options for the forwarded message). Is my understanding correct? Pavlos
