Hi,
I've been attempting, unsuccessfully, to configure haproxy to reverse proxy
HTTP requests (/maps context) to the HTTPS Google maps API. Network traces
show empty data packets coming back from Google which appear to be
interpreted as 503/bad gateway by haproxy. I've modified the haproxy
config through various attempts to get this working (commented out lines)
but still no success. I've compared successful reverse proxy requests
processed by Apache and the request headers are identical (cookie order is
different). My config below:
defaults
mode http
log global
option httplog
option tcplog
# option dontlognull
option http-server-close
# option forwardfor except 127.0.0.0/8
# option forwardfor

timeout http-request 10s
timeout queue 100s
