Overview

HTTP::Client that splits connection setup into DNS, TCP connect and TLS handshake timings.

HTTP::Client resolves and connects lazily inside its private #io, so overriding that is the only place the three phases can be measured separately without giving up automatic reconnection when a keep-alive connection is dropped. Handing a pre-connected socket to HTTP::Client.new(io, ...) would measure the phases just as well but marks the client non-reconnectable, which turns every server-side keep-alive timeout into a hard failure. That is also why the HTTPS-over-proxy CONNECT tunnel is opened here rather than by the caller.

Constructors

• .new(host : String, port = nil, tls : HTTP::Client::TLSContext = nil, tunnel : Tunnel | Nil = nil)

Instance Method Summary

• #connections_opened : Int64
• #last_connect_ms : Float64
• #last_dns_ms : Float64
• #last_tls_ms : Float64 | Nil

  Nil when the last connection carried no TLS handshake, so a plain HTTP run reports zero handshakes instead of a run of zero-millisecond ones.
