hi!
yes, i am running SQUID-2.3.STABLE4 but without asyncufs ...
i think i got it ...
what i am doing is running a trace thru a cache ... and then cleaning the
whole cache. After that i run the same trace but the cache has a parent
(the parent has all the trace objects in its cache).
so the child cache thinks that it is in the memory, but since the cache is
empty it gives TCP_SWAPFAIL_MISS, and then falls back to cache_miss
processing and gets it from the parent.
corrct me if i am wrong....

thanks
