 8      This is an https connection that verifies that the server certificate is signed by 
 9      a trusted ca_cert. 
10   
11      NOTE that it does NOT validate that the hostname matches the one in the certificate, 
12      because multiple clients (with different hostnames) will use the same certificate. 
13      Thus, for us it's enough to know that a given client has the private key whose public 
14      key is trusted.
