Referencing backend definition in one include file from another include file

[Bjorn Jungskar]

Hi,

I have one Varnish VCL file that has two include statements, one that
allows for custom backend definitions and one that allows for custom
URL mappings. The problem is that I get compilation errors when
referencing the backend defined in the included file from the other
included file.

Example:

main.vcl:
------------
backend default {
  .host = "127.0.0.1";
  .port = "8080";
}
include "custom_backends.vcl";

sub vcl_recv {

  if ( req.url ~ "/someurl/" ) {
    req.backend = default;
    return (pass);
  }

  include "custom_mappings.vcl";

}

custom_backends.vcl:
--------------------------------
backend mybackend {
  .host = "127.0.0.1";
  .port = "1234";
}

custom_mappings.vcl:
--------------------------------
 if ( req.url ~ "/some_other_url/" ) {
    req.backend = mybackend;
    return (pass);
 }


Also, it is not possible to define the custom backends directly in the
custom_mappings file since a backend can not be defined inside a
function. Is there any way to get around this problem?
