Module proxy 

HTTP CONNECT proxy support.

Corporate firewalls often expose an HTTP CONNECT proxy (Squid, Blue Coat, Zscaler, etc.). This module implements the client side: open a TCP connection to the proxy, send CONNECT target:port HTTP/1.1, parse the 200 Connection established response, and return the underlying TcpStream which is now tunneled to the target.

SOCKS5 is out of scope for Phase 1 — see notes/TODO.md.

Structs

ProxiedConnection

A connection that routes through a local TCP listener backed by an HTTP CONNECT proxy. Used for backends (MySQL, MSSQL, Oracle) that do not accept a pre-built stream.

ProxyConfig

Parsed proxy configuration.

Functions

is_no_proxy

Check whether the target host is covered by the NO_PROXY environment variable.

resolve_proxy_from_env

Resolve proxy configuration from the standard environment variable stack.
