I double-checked my refresh_pattern, which says:

,-----
| # 3 * 24 * 60 = 4320, 5 * 24 * 60 = 7200
| refresh_pattern . 4320 60% 7200
`-----

As you can see, no reload-into-ims or ignore-reload is set.

Doing a diff with the original .conf, I noticed the only reason
might be that I've turned the offline mode on:

Is it the culprit? Oh, I'm too curious to give it a try...

YES, that's it! (*1)

I think this should be called a bug, not a feature. Squid should
still honor the 'Pragma: no-cache' request even in offline mode.
For this will be the only way to refresh a cached page in offline
mode.

I took the liberty to send a copy to
squid-bugs@squid-cache.org. Hope it will not bounced back to me.

Thanks

Tong.

PS.

Relevant info for Squid bug report:

# Squid version: squid-2.4.STABLE7, Vendor: Red Hat, Inc.
# Operating System: RH8, with kernel upgraded

$ cat /proc/version
Linux version 2.4.20-20.8 (bhcompile@daffy.perf.redhat.com) (gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)) #1 Mon Aug 18 14:39:22 EDT 2003

Note:

*1: After disabling the (only) offline_mode, it works now:

    $ client -rv http://localhost/~tong/test/
    headers: 'GET http://localhost/~tong/test/ HTTP/1.0
    Pragma: no-cache
    Accept: */*

    '
    HTTP/1.0 200 OK
    Date: Tue, 25 Nov 2003 15:20:47 GMT

    Content-Length: 1182
    Content-Type: text/html; charset=ISO-8859-1
    X-Cache: MISS from xpt
    Proxy-Connection: close

The previous respond was:

    $ client -vr http://localhost/~tong/test/
    headers: 'GET http://localhost/~tong/test/ HTTP/1.0
    Pragma: no-cache
    Accept: */*

    '

    [...]

The page was still an old copy.
