1659 | * or have a default application level protocol. | |
1660 | * | |
1661 | * 2) If the server supports NPN, but advertises an empty list then the | |

1663 | * API that this fallback case was enacted. | |
1664 | * | |
1665 | * 3) Otherwise, the client finds the first protocol in the server's list | |
1666 | * that it supports and selects this protocol. This is because it's | |
1667 | * assumed that the server has better information about which protocol | |
1668 | * a client should use. | |
1669 | * | |
1670 | * 4) If the client doesn't support any of the server's advertised | |
1671 | * protocols, then this is treated the same as case 2. | |
1672 | * | |
1673 | * It returns either | |
