      Description

      It's not possible to use the default Varnish template on Varnish versions lower than 5.1. Varnish service fails to start with:

       varnish.service - Varnish HTTP accelerator
         Loaded: loaded (/lib/systemd/system/varnish.service; enabled; vendor preset: enabled)

      Looks like it's related to this change:
      https://github.com/ezsystems/ezplatform-http-cache/commit/fc6117d4435d28907429b686fae3d7d103028b9f

      Seems like implicit casting has been added in 5.1 (5.1.3 doc mentions it https://varnish-cache.org/docs/5.1/reference/vcl.html?highlight=vcl#booleans , but 4.1.10 does not: https://varnish-cache.org/docs/4.1/reference/vcl.html?highlight=vcl#booleans ).

      Katarzyna Zawada encountered this issue on varnish-5.0.0.
