What you are trying to do should just work, and I cannot spot an error in your
VCL with regards to the ban handling.
But your use of the Vary header looks wrong, It is not a request header but
rather a response header (which you need to set in vcl_backend_response) and
also the value if the Vary header is the name of a request header.
So in your case it should be something like:
sub vcl_backend_response {
if (beresp.http.Vary) {
set beresp.http.Vary = beresp.http.Vary + ", X-BOLT-SITE-LOCALE"; }
else { set beresp.http.Vary = "X-BOLT-SITE-LOCALE";
}
}
