Overview
Parses HTTP/1.x requests and dispatches them to the Rack application. Coordinates with the Ractor pool for parsing and with the reactor for requests that need more data before they can be handled.

Class Method Summary collapse

Hostheader per RFC 9112 section 3.2, where a valid value is a non-empty single-value line. -

Returns true when an HTTP/1.1 request lacks a valid Host header per
RFC 9112 section 3.2, where a valid value is a non-empty single-value
line.

.parse(data, env_template, max_body_size) ⇒ Hash

:malformed or :too_large; incomplete input returns the state
so the reactor can wait for more.
