Summary

Add support for HTTP compression in HAProxy responses.

Details

HAProxy can be configured to compress HTTP response bodies for specified mine-type's that are not already compressed by backend servers.
The key advantage of this is reduction of network bandwidth and latency to clients.

Example of how this could be configured in VyOS:

set load-balancing haproxy service https-frontend http-compression algorithm 'gzip'
set load-balancing haproxy service https-frontend http-compression mime-type 'text/css'
set load-balancing haproxy service https-frontend http-compression mime-type 'text/html'
