Hi,<br>
<br>
I have a varnish server sat in front of a website which was previously<br>
sitting at 60% hitrate, no hit_for_pass. With no configuration change<br>
aside from adding a single ban rule (which I have since removed) keyed<br>
to a hostname the site runs (but which accounts for a tiny fraction of<br>
the traffic), this has gone to 1% hitrate, 99% hit_for_pass. Headers<br>
being sent out suggest caching is still behaving as expected but the shm<br>
tools all report this high hit_for_pass rate. Looking at the number of<br>
objects, there's now nothing but object heads in the store.<br>
<br>
Any thoughts on what could be going on here?<br>
<br>

Cheers,<br>
James Harrison<br>
