Given this: $url = 'http://' . <something broken>'' # I can't guarantee that what's broken for me now will be when you get to this bug! $file = "foo.txt"; $verbose = 2; $ua = LWP::UserAgent->new; print STDERR ("Contacting $url for $file\n") if( $verbose > 1 ); my $rsp = $ua->mirror( $url, $file ); unless( $rsp->is_success || $rsp->code == 304 ) { # Yes, even if $verbose == 0 my $peer = $rsp->header( 'Client-Peer' ) || ''; $peer = " from $peer" if( $peer ); print STDERR ("ERROR: ", $rsp->status_line, "$peer\n"); } I get: Contacting ... for ... Result: 500 Status read failed: Connection reset by peer #<< no $peer Dumping the $rsp, we see that 'Client-Peer' is not set. It would be useful to report which server is resetting the connection so it can be fixed :-) Although this example shows a read failing, I assume that a write (e.g. sending the request) can also fail without setting the Client-Peer header. Note that it's not as simple as reporting the URL in the client - redirects and multi-homed hosts require that LWP actually set the header from the failing socket, as it does for other errors; e.g. 404. libwww-perl V6.10 Thanks. --------------------------------------------------------- This communication may not represent my employer's views, if any, on the matters discussed.
