Consistent Hashing to a Dynamic Set of Servers Based on TCP Payload
In the HAProxy 2.1 can you use aes_gcm_dec(...) in combination with req.payload(...) for such a requirement.
My idea, untested.
listen tcp-in bind :443 ssl cert tcp-request inspect-delay 10s tcp-request session set-var(sess.routingkey) req.payload(0,500) # for consistent hashing try this hash-type consistent wt6 use_backend %[var(sess.routingkey),aes_gcm_dec(128,txn.nonce,Zm9vb2Zvb29mb29wZm9vbw==,txn.aead_tag)]Here are also the links to the html Documentation.
