HTTP Echo Server

The `http-echo-server` package provides a minimalist HTTP server designed primarily for debugging and testing network requests. It accepts any TCP connection and immediately echoes back the entire incoming TCP content as an HTTP response. Crucially, it does not parse or understand the HTTP protocol, meaning it will respond with the raw bytes received, including headers and body, without interpretation. The server will terminate the TCP connection exactly 2 seconds after the first data packet is received, regardless of whether the full request has arrived. This behavior makes it unsuitable for production environments or as a general-purpose HTTP server but highly effective for inspecting raw network traffic. The current stable version is 2.1.1. Given its utility nature, the release cadence is likely infrequent, driven by bug fixes or minor enhancements. Its key differentiator is its deliberate simplicity and lack of HTTP protocol understanding, making it a 'transparent pipe' for raw request inspection.
