The main
problem when I try to check monitong string on server side from client, the original behaviour will push the connection to the load balancer if I try to connect to www.example.com and then the load balancer will handed off the connection to a random server.
If I want to connect directly to each server servers so I’ll need to use
their IP address. This approach would look something like:
curl --verbose 'http://x.x.x.x:xxxx/monitoring_file.html'
But
since the servers use name-based virtual hosts so we’d get a 404 error
back. The trick is to have curl send the proper host header:
curl --verbose --header 'Host: www.example.com' 'http://x.x.x.x:xxxx/the_url_to_test'
