セッションプロトコル

Traffic Server supports some session level protocols in place of or on top of HTTP. These can be provided by a plugin (see 新規プロトコルプラグイン) or be one that is supported directly by Traffic Server.

Session protocols are specified by explicit names:

  • http/0.9

  • http/1.0

  • http/1.1

  • http/2

プロキシーポート上でサポートされるセッションプロトコルはこれらの値のサブセットになります。利便性のためにいくつかの擬似的な値が下記の基本的なプロトコルとして定義されています。

  • http は http/0.9 、http/1.0 、 http/1.1 を意味します。

  • http2 は http/2 を意味します。

Each proxy port can be configured in proxy.config.http.server_ports to support a subset of these session protocols. For TLS enabled connections this configuration controls which protocols are offered by ALPN and NPN. Protocol sniffing is use for non-TLS proxy ports to determine which protocol is being used by the client. If the detected protocol is not supported for that proxy port the connection is dropped.

Support for NPN is deprecated, and it will be removed on a future release.
