Fields
RequestVersionExact | 2 | Only use the requested version. This option allows for use of a prenegotiated clear text connection for the requested version. |
RequestVersionOrHigher | 1 | Use the highest available version, downgrading only to the requested version but not below. If the server supports a higher version than the requested version (either negotiated via ALPN (H2) or advertised via Alt-Svc (H3)) and a secure connection is requested, the result is the highest available version. Otherwise, the version downgrades to Version. This option allows use of a prenegotiated clear text connection for the requested version but not for a higher version. |
RequestVersionOrLower | 0 | Use the requested version or downgrade to a lower one. This is the default behavior. If the server supports the requested version, either negotiated via ALPN (H2) or advertised via Alt-Svc (H3), and a secure connection is being requested, the result is the Version. Otherwise, the version downgrades to HTTP/1.1. This option does not allow use of a prenegotiated clear text connection, for example, H2C. |
