Unfortunately, no. Pipe connections are correctly configured to close by this config :

sub vcl_pipe
{
     set req.http.connection = "close";
}

And besides that: When I monitor all requests for this site (lets call it site X), I see only GET and POST requests and nothing that should trigger 'pipe mode' for this site. There are other sites also running on the Varnish server, some of which trigger 'pipe mode' sometimes, but these sites use seperate backends, so this should be of no influence to the traffic to site X.
