Your responses are probably being cached because of the default
default_ttl setting, which you'll find detailed a little way down
https://www.varnish-cache.org/docs/3.0/reference/varnishd.html#run-time-parameters
.
However, rather than changing that run-time setting, you may want to
force Varnish always to contact the back-end next time for those
resources which don't dictate an explicit TTL. This would be both more
visible and more tunable, later on.
This VCL would achieve that goal, I believe (untested, but taken from the
docs):
sub vcl_fetch {
if (beresp.ttl <= 0s) {
# Mark as "Hit-For-Pass" for the next 2 minutes
set beresp.ttl = 120s;
return (hit_for_pass);
}
}
HTH,
Jonathan

Hello everyone,
Can someone please share answers to my questions:
1. I am using regular linux and downloaded Varnish Cache 3.0.2
varnish-3.0.2.tar
where do I put the files?
2. I read here
https://www.varnish-cache.org/docs/3.0/installation/install.html#source-or-p
ackages to run commands, but don't know where am to be to run the backups.
- should I be in one of the folders in the tar file above to run the
commands?
3. What messages should I see to confirm that Varnish is properly
installed?
4. Please share any other pertinent information.

What kind of Linux is that? You might want to specify your choice of
Linux distribution, so we can help you better. Given proper information,
Varnish will probably be way easier to install than what you're
currently doing.

Then the proper release is available as documented at
https://www.varnish-cache.org/releases/varnish-cache-3.0.2.

No such luck. Please see
https://www.varnish-cache.org/installation/redhat. Varnish is a power
tool for experienced administrators and if you're not able to install it
without step-by-step instructions, Varnish might not be what you're after.
> Have a good day!
You too, and for future reference please 1) respond to the list, and 2)
stop top-posting.
