[squid-users] weird refresh problem with reverse proxy

Hi,

I'm using squid as a reverse proxy for a bunch of sites... these sites
are running a heavy cms system and the setup is that squid serves all
pages as static (even if the cms is down... all cached pages are shown
w/o errors)... when pages are updated, a custom script calls an external
purge program which reads all related url's from the squid cache and
sends PURGE requests to squid...
everything works fine... except that most of the time, after pages have
been PURGEd, a customer who uses Internet Explorer keeps seeing old
versions of the pages... *untill* I press Shift reload on the same page
with my Mozilla browser and then immediately the customer sees the
updated version too after a reload (my mozilla and the IE are in
completely different networks so we don't share any resources)...
does this make sense at all? could it be that mozilla somehow can force
squid to do updates which IE can't do?

here's part of the config, which is probably related to this problem:

refresh_pattern . 10080 0% 10080 override-lastmod
ignore-reload override-expire reload-into-ims

(yes, I know, this is against the rfc's... ;))

Regards,

Ricardo.
