UpgradeEncapsulation

rama::icap::http

Enum UpgradeEncapsulation

pub enum UpgradeEncapsulation {
    Keep,
    Omit,
}

Available on crate features http and icap only.

Expand description

How encapsulated HTTP heads carry a protocol upgrade: an HTTP/1.1 Upgrade, or the :protocol of an HTTP/2 or HTTP/3 Extended CONNECT, which is encapsulated as the GET upgrade it stands for, and its 2xx acceptance as a 101 (RFC 8441 §5).

RFC 3507 §4.4.2 omits hop-by-hop fields from encapsulated heads; established ICAP clients keep Upgrade, so a service tells an upgrade from a plain GET. Connection is never encapsulated. Without Upgrade an acceptance stays the 2xx it was, as a 101 must name its protocol.

Variants§

Keep

Keep the Upgrade field, as established ICAP clients do.

Omit

Omit it with the other hop-by-hop fields.
