/* 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.
