I don't know if this is a weird bug or my lack of vcl knowledge, so here
we go:
I want this behavior: When somebody hits <ctrl>-F5 in a browser, varnish
will purge the current page from the cache.
Firefox puts this in its request header when you do that:
Cache-Control: no-cache
So I inserted this piece of vcl:
--
sub vcl_hit {
if(req.http.Cache-Control == "no-cache") {
set obj.ttl = 0s;
error 200 "Hey, we got a purge";
}
}
--
At first glance that kind of works. When somebody hits <ctrl>-F5 the
page gets purged and I get my custom error message.
However suddenly the page is not served from the cache _at all_. That is
unless I just hit F5, _then_ I get a cached page. Hitting F5 sends this
request header in Firefox:
Cache-Control: max-age=0
I don't send any caching headers on the backend if that matters, just
relying on the default Varnish fallback to 120 sec.
Any ideas?
