Re: Varnish is not always adding X-Forwarded-For
[In reply to]

I had a close at the end of the pipe:
sub vcl_pipe {
set bereq.http.X-Forwarded-For = req.http.X-Forwarded-For;
set bereq.http.X-Forwarded-For = regsub(bereq.http.X-Forwarded-For,
"$", ", ");
set bereq.http.X-Forwarded-For = regsub(bereq.http.X-Forwarded-For,
"$", client.ip);
set req.http.connection = "close";
}
It still isn't working as we had hoped.
Sincerely,
