See the r->header_in buffer. You can look into the implementation of
the ngx_echo module's $echo_client_request_body variable for details:

Use error_page 400 to capture requests with invalid headers because
the nginx header parser will throw an exception immediately when it
sees invalid headers. And the "garbage" will still be in r->header_in
but may be incomplete.
