Some content is simply not cacheable. The hint there is the word *live*.
Content from a cache is never "live" - it is *old* / past / previous /
outdated / obsolete.

VERY bad idea. 'no-store' and similar HTTP violations should be
performed as conservatively as possible. Only applied as a last resort
to fix a specific sites problems.

This breaks *other* caches on machines upstream or downstream of yours.
It has no effect on your proxy. Please remove.

This is the default behaviour for Squid. You can remove the above line.

Difficult to say without the details you have removed.

Take a visit to redbot.org and paste the full URL - include the domain
name and query-string parameters which are not being logged. It will
tell you whether the resource is cacheable and why or why not.
