Set up Varnish with heroku app - what backend host and port do i use? -

i'm trying set varnish server heroku app. i'm having difficulties setting backend host , port point heroku app.

i tried entering this:

backend default {     .host = "gavedrysset-api.herokuapp.com";     .port = "80"; }

this not work , giving me heroku error page saying this:

heroku | no such app  there no app configured @ hostname. perhaps app owner has renamed it, or mistyped url.

how can make varnish point heroku app?

i figured out solution. have no idea doing though... found answer in this thread.

i added default.vcl:

sub vcl_recv {     set req.http.host = "gavedrysset-api.herokuapp.com"; }
