1.1b11 and stale neighbors...

Well, as discussed a while ago the very welcome change in beta11 now
makes it obvious that there's a need to guard against stale neighbors.
In my case a beta10 sib feeds old objects to the main beta11 parent,
like this:

846780336.393    101 aichan.swb.de TCP_REFRESH_MISS/200 939 
GET http://www.unitedmedia.com/rib_bar_wh.gif - SIBLING_UDP_HIT_OBJ/washuu.swb.de
The object is stale (and has in fact changed ^_-) according to rules on
aichan, but the UDP_HIT is obviously taken as gospel.
I see two solutions, the short term one is to subject an UDP_HIT object
to the same rules as one from the local cache.
The long term one would involve the addition of suitable fields/commands
in the ICP stack and thus avoiding the transfer of objects that are 
considered stale locally. ^_^
Oh btw, I hope Iain Lea is still reading this, your squid-stats needs
an overhaul now, after including TCP_REFRESH_HIT with the TCP_HIT counts
the stats look very bright again. ^_-
The cachemgr utilization output though is now 20% of the corrected
squidstat output, gotta wait a day to see how this settles. ^_^
