* Client and server exchange these certificates during the handshake phase of a TLS connection.

 * ### Server Authentication
 *
 * This is the most common form of TLS authentication: clients verify that servers are trusted and
 * that they own the hostnames that they represent. Server authentication is required.

 * To perform server authentication:

They're also concrete: each URL identifies a specific path (like `/square/okhttp`) and query (like `?q=sharks&lang=en`). Each webserver hosts many URLs.
