+	    Do not use chunked-encoding with 1xx, 204 and 304
+	    responses when using mod_esi. Old behavior was not
+	    compliant with HTTP/1.1 RFC and could cause clients to
+	    hang when they received 1xx, 204 or 304 responses that
+	    included an empty chunked-encoded body.</p>

+	    Add robust handling of chunked-encoded HTTP responses
+	    with an empty body (1xx, 204, 304). Old behavior could
+	    cause the client to hang when connecting to a faulty
+	    server implementation.</p>
