           Summary: mod_proxy proxy_http should flush data when it receives
                    flush from the backend server.
           Product: Apache httpd-2.0
           Version: 2.1-HEAD
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: janne@abako.fi


When proxy_http receives flush from the backend server streaming data, it should
flush data to the client.


This code does the thing:

modules/proxy/proxy_http.c:


                   /* found the last brigade? */
                    if (APR_BUCKET_IS_EOS(APR_BRIGADE_LAST(bb))) {
                        /* if this is the last brigade, cleanup the
                         * backend connection first to prevent the
                         * backend server from hanging around waiting
                         * for a slow client to eat these bytes
                         */
                        ap_proxy_http_cleanup(r, p_conn, backend);
                        /* signal that we must leave */
                        finish = TRUE;
+                    } else {		     		      
+		      apr_bucket *e;
+		      e = apr_bucket_flush_create(c->bucket_alloc);
+		      APR_BRIGADE_INSERT_TAIL(bb, e);
		    }
