| /** HTTP2 Clear Text Connection factory. |
| * <p>This extension of HTTP2ServerConnection Factory sets the |
| * protocol name to "h2c" as used by the clear text upgrade mechanism |
| * for HTTP2 and marks all TLS ciphers as unacceptable. |
| * </p> |
| * <p>If used in combination with a {@link HttpConnectionFactory} as the |
| * default protocol, this factory can support the non-standard direct |
| * update mechanism, where a HTTP1 request of the form "PRI * HTTP/2.0" |
| * is used to trigger a switch to a HTTP2 connection. This approach |
| * allows a single port to accept either HTTP/1 or HTTP/2 direct |
| * connections. |
