Hi,
Is there any way to check if a particular request was answered "in grace" by
sending a HTTP header?
I'm trying to increase the grace period if the user-agent contains "Googlebot"
in order to speed up crawling response time and consequently be better
positioned in Google organic search results. When I access using Googlebot in
the user-agent header I'm not sure if Varnish is waiting for a backend request
or not.
VCL excerpt:
sub vcl_recv {
...
# Set Grace
if (req.http.user-agent ~ "Googlebot") {
set req.grace = 12h;
} else {
set req.grace = 30m;
}
...
}
sub vcl_fetch {
...
# Set Grace
set beresp.grace = 12h;
...
}
Thanks,
Carlos Cima _______________________________________________
