	//
	// Depending on the HTTP client software, HTTP protocol version,

	// it may not be possible to read from the Context.Request().Body after writing to the context.ResponseWriter().
	// Cautious handlers should read the Context.Request().Body first, and then reply.
	//
	// Except for reading the body, handlers should not modify the provided Context.
	//

	// It recovers the panic, logs a stack trace to the server error log, and hangs up the connection.
