Somehow, Varnish seems to save the website in cache:
- VCL_call DELIVER
- VCL_return deliver
VCL Configuration:
vcl 4.0;
# Default backend definition. Set this to point to your content server.
backend default {
.host = "127.0.0.1";

}
sub vcl_recv {
// Remove all cookies except the session ID.
if (req.http.Cookie) {

}
}
}
sub vcl_backend_response {
# Happens after we have read the response headers from the backend.
#
# Here you clean the response headers, removing silly Set-Cookie headers
# and other mistakes your backend does.
if (beresp.http.Surrogate-Control ~ "ESI/1.0") {
unset beresp.http.Surrogate-Control;
set beresp.do_esi = true;
}
}
sub vcl_deliver
{
# Insert Diagnostic header to show Hit or Miss
if (obj.hits > 0) {
set resp.http.X-Cache = "HIT";
set resp.http.X-Cache-Hits = obj.hits;
}
else {
set resp.http.X-Cache = "MISS";
}
}
What is wrong there?

Answer 1

You shall not cache pages with a Set-Cookie Header!
also you are quoting the wrong lines to determine whether it was cached or not:
VCL_call MISS
