reverse-proxy : HTTP Keep-alives do not work if/when I leverage keep-alive configuration options in reverse-proxy

[sarfarazahmad89]

Apologies for doing a rough brain dump here but if/when i set keepalive options in reverse proxy, they seem to be breaking underlying http.Transport's keepalive option (HTTP Keepalives) . I have tested this in action with tcpdump, but will attempt to dissect the code and update here if/when I find the bug. Unsetting the keepalive options, seems to be doing the trick. I had set

-                keepalive 5m
-                keepalive_interval 15s
