The uWSGI protocol uses a 4-byte binary header: - Byte 0: modifier1 (packet type, 0 = WSGI request) - Bytes 1-2: datasize (16-bit little-endian, size of vars block) - Byte 3: modifier2 (additional flags, typically 0) After the header: 1. Vars block (datasize bytes): Key-value pairs containing WSGI environ - Each pair: 2-byte key_size (LE) + key + 2-byte val_size (LE) + value 2.

Header Mapping (CGI/WSGI to HTTP): The uWSGI protocol passes HTTP headers using CGI-style environment variable naming. This method converts them back to HTTP header format: - HTTP_* vars: Strip 'HTTP_' prefix, replace '_' with '-' Example: HTTP_X_FORWARDED_FOR -> X-FORWARDED-FOR Example: HTTP_ACCEPT_ENCODING -> ACCEPT-ENCODING - CONTENT_TYPE: Mapped directly to CONTENT-TYPE header (CGI spec excludes HTTP_ prefix for this header) - CONTENT_LENGTH: Mapped directly to CONTENT-LENGTH header (CGI spec excludes HTTP_ prefix for this header) Note: The underscore-to-hyphen conversion is lossy. Headers that originally contained underscores (e.g., X_Custom_Header) cannot be distinguished from hyphenated headers (X-Custom-Header) after passing through nginx/uWSGI. This is a CGI/WSGI specification limitation, not specific to this implementation.
