301cb0ef41Sopenharmony_ci// Sending back a chunked response to an HTTP/1.0 client would be wrong,
311cb0ef41Sopenharmony_ci// so what has to happen in this case is that the connection is closed
321cb0ef41Sopenharmony_ci// by the server after the entity body if the Content-Length was not
331cb0ef41Sopenharmony_ci// sent.
341cb0ef41Sopenharmony_ci//
351cb0ef41Sopenharmony_ci// If the Content-Length was sent, we can probably safely honor the
361cb0ef41Sopenharmony_ci// keep-alive request, even though HTTP 1.0 doesn't say that the
371cb0ef41Sopenharmony_ci// connection can be kept open.  Presumably any client sending this
381cb0ef41Sopenharmony_ci// header knows that it is extending HTTP/1.0 and can handle the
391cb0ef41Sopenharmony_ci// response.  We don't test that here however, just that if the
401cb0ef41Sopenharmony_ci// content-length is not provided, that the connection is in fact
411cb0ef41Sopenharmony_ci// closed.
