How to compare 'bereq.backend' and 'req.backend_hint' against a director/backend in Varnish 4.1

Hi Dridi,

thanks for your comment.

 From the log output for:

std.log("xxxxxxxx-vcl_backend_response-bereq: " + bereq.backend);
std.log("xxxxxxxx-vcl_backend_response-beresp: " + beresp.backend);
...	
std.log("xxxxxxxx-vcl_deliver: " + req.backend_hint);


**** v1    1.0 vsl|       1002 VCL_Log         b xxxxxxxx-vcl_backend_response-bereq: d1
**** v1    1.0 vsl|       1002 VCL_Log         b xxxxxxxx-vcl_backend_response-beresp: b1
...
**** v1    1.0 vsl|       1001 VCL_Log         c xxxxxxxx-vcl_deliver: d1

I got the impression that both "req.backend_hint" and "bereq.backend" hold the director (because they both output "d1") and that only "beresp.backend" holds the backend (because it outputs "b1").
Therefore I assumed that a comparison against "d1.backend()" would work for "req.backend_hint" and "bereq.backend" but not for  "beresp.backend".

Best,
Ronald
