I’ve configured a backend server as follows:
server servername www.example.com:443 ca-file /etc/haproxy/GeoTrustSSLCA.crt check-ssl ssl force-tlsv12 verify required verifyhost xyz weight 200 observe layer7 check
When does HAProxy perform the DNS resolution on www.example.com:
each HTTP request?
The reason we’re using the domain name vs. the IP address is that the service to which we’re connecting says they may change the IP from time to time of both their primary and their backup servers.
