2021 | * string may be truncated. The current, but experimental algorithm for | |
2022 | * selecting the protocol is: 1) If the server doesn't support NPN then this | |
2023 | * is indicated to the callback. In this case, the client application has to | |
2024 | * abort the connection or have a default application level protocol. 2) If | |
2025 | * the server supports NPN, but advertises an empty list then the client | |
2026 | * selects the first protcol in its list, but indicates via the API that this | |
2027 | * fallback case was enacted. 3) Otherwise, the client finds the first | |
2028 | * protocol in the server's list that it supports and selects this protocol. | |
2029 | * This is because it's assumed that the server has better information about | |
2030 | * which protocol a client should use. 4) If the client doesn't support any | |
2031 | * of the server's advertised protocols, then this is treated the same as | |
2032 | * case 2. It returns either OPENSSL_NPN_NEGOTIATED if a common protocol was | |
2033 | * found, or OPENSSL_NPN_NO_OVERLAP if the fallback case was reached. | |
