RE: Boku upstream unavailable alerts

Hi Shawn,

Sort of a "pseudo" chain, since I believe only Firewall chaining is
actual chaining. When you don't have direct communication with the
upstream Web Proxy service, you're not chaining, you're just a SecureNAT
client. Is that the case?

Thanks!
Tom

Yes, sorta.  The ISA's the only thing that caches.  More of a chain than
a
hierarchical cache.

Hi Shawn,

As you using hierarchical Web proxy caching?

Thanks!

I am getting monstrous numbers of 'The Web Proxy service detected that
the
upstream proxy 'xxxx' is not available.' alerts, sometimes in the
neighborhood of 10 / second.  It mostly happens around lunch which is of
course the busiest time for the proxy.  Anyone know exactly fires those
events?  Is it simply a failed connection when trying to forward a
request
or what?  Do I need to tune the ip stack on the box maybe?  Nobody's
griping
about degraded services (thank God), but I want to fix the problem so
that
it doesn't escalate into end-user-griping.
