My idea is to use nginx to do compression for back-end servers. HAProxy or Varnish does not support
such feature. I don't need nginx to do load balance and persistence but only compression. LVS doing
an outstanding job on load balancing and session handling (persistence) while pulse (piranha) doing
helthchecks and failovers.
I have read some post of persistence+round robin within nginx which seems to be not successful.
Any suggestion is much appreciated.
