No, ignore-reload means ignore the Ctrl+F5 / reload button headers

The design model for Squid caching is "shared cache". Which means
strictly following RFCs Cache-Control:private content is not allowed to
be stored. Doing so in a shared cache design causes big problems.
We get around that danger in Squid by doing the revalidations. For most
traffic it should work find and reduce bandwidth. For some it does not.
But the worst-case there is no different from the proxy having done what
was mandatory to do in the first place.
