Because the connection remains encrypted, HAProxy can't do anything with it other than redirect a request to another server. This is HAProxy's preferred way to read an SSL certificate. For example, if our local server exists at 192.168.33.10, but then our Virtual Machine IP changes to 192.168.33.11, then we don't need to re-create the self-signed certificate. Currently HAProxy requires the certificate+private key to be in a single PEM file (the crt option).
