You might try Stack Overflow if you're not having any luck on this list.
There are a few folks who answer Varnish questions on there. Just tag it
"varnish" and "varnish-vcl".

Hi all,
I'm a bit newish to Varnish though I do have some background. I have
a Varnish 5 instance connected to 2 backend servers (Magento 2
applications).
I'm using the new Varnish 5 feature of loading multiple VCL files.
My ultimate problem is during purging however I'd like to ensure
things are set up correctly because documentation regarding multiple
VCL files in Varnish 5 is somewhat lacking.
To keep things very simple for now, I'm going to use 1 backend
server in my example.
So, I have a magento.vcl defined as follows:
*vcl 4.0;*
*import std;*
*
*
*# The minimal Varnish version is 4.0*
*# For SSL offloading, pass the following header in your proxy
server or load balancer: 'X-Forwarded-Proto: https'*
*
*
*backend default {*
* .host = "127.0.0.1";*
* .port = "8088";*
*}*
*
*
*include "/etc/varnish/common.vcl";*
And a top.vcl
*vcl 4.0;*
*
*
*import std;*
*
*
*backend default { .host = "127.0.0.1"; }*
*
*
*sub vcl_recv {*
* if (req.http.host == "magento2.dev") {*
* return (vcl(magento_vcl));*
* }*
*}*
Then I run
*service varnish restart*
*varnishadm*
*vcl.load magento /etc/varnish/conf.d/magento.vc <http://magento.vc>l*
*vcl.label magento_vcl magento*
*vcl.load top /etc/varnish/top.vcl*
*vcl.use top*
*quit*
When I browse to magento2.dev, I get a backend fetch error after
some seconds. It's only when I go in magento.vcl and change the name
of the backend and make a backend hint that it works. See below:
*vcl 4.0;*
*import std;*
*
*
*# The minimal Varnish version is 4.0*
*# For SSL offloading, pass the following header in your proxy
server or load balancer: 'X-Forwarded-Proto: https'*
*
*
*backend magento {*
* .host = "127.0.0.1";*
* .port = "8088";*
*}*
*
*
*
sub vcl_recv {
set req.backend_hint = magento;
}
*
*
*
*include "/etc/varnish/common.vcl";*
*
*
Why should I be specifying a backend hint? Shouldn't Varnish be
loading a different VCL according to the host specified in top.vcl?
Or is there something wrong?
Thanks in advance,
Kurt
