Мы пытаемся заставить Varnish кэшировать запросы диапазона. Мы используем Varnish 4.0.
Мы следующие конфигурации
vcl 4.0;
import std;
# Default backend definition. Set this to point to your content server.
backend default {
.host = "194.142.x.x";
.port = "8008";
}
sub vcl_recv {
if (req.url ~ "(?i)\.(png|avi|mkv|mp4)(\?[a-z0-9]+)?$") {
unset req.http.Cookie;
}
# Happens before we check if we have this in cache already.
#
# Typically you clean up the request here, removing cookies you don't need,
# rewriting the request, etc.
set req.http.host = regsub(req.http.host, "v\.","\rms\.");
std.log("REWRITED TO"+req.http.host+" "+req.url);
}
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.
}
sub vcl_deliver {
# Happens when we have all the pieces we need, and are about to send the
# response to the client.

как всегда запросы диапазона обслуживаются слишком долго, поэтому мы чувствуем, что они не кэшируются, поскольку исходный сервер поражен.
