Squid has no control over the client/browser choice of when to
re-request an object. The URL you presented results in a *private*
response so both proxies are supposed to have nothing to do with it
beyond network fetch and delivery.

The URL also has several other major problems which could be screwing up
the browser:

I don't see any evidence of a problem in the proxies. It all appears to
be browser and server issues.
