Odd. Should not happen.

Hmm.. check the clocks on the two servers (the proxy and the
authentication server). I can imagine that if the clock on the
authentication server is running ahead of the proxy then unexpected
things may happen in combination with that bug..

Please add access.log details with log_mime_hdrs on to the bug report,
showing the problem..

When I saw the 302 problem it looked harmless, causing Squid to cache
the 302 but always ignore them on cache hits..
