/* Server Name Indication (SNI) tests
 * 
 * This test relies on https://sni.velox.ch/ and thus is disabled by default.
 *
 * sni.velox.ch uses 3 certificates :
 * - CN=alice.sni.velox.ch (sent in response to server_name = alice.sni.velox.ch or not set)
 * - CN=bob.sni.velox.ch (sent in response to server_name = bob.sni.velox.ch)
 * - CN=*.sni.velox.ch (sent in response to server_name = mallory.sni.velox.ch or *.sni.velox.ch or sni.velox.ch)
 *
 * The test sends requests to the server, sending different names, and checks which certificate
 * the server returned.
