The first request through cache is usually expected to MISS, its the
second which tells you whether or not the caching was success/failure.

Try:
   squidclient -h 10.94.206.34 -p 8001 "/admin?op=ping"
   squidclient -h localhost -p 8001 "/admin?op=ping"
   squidclient -h localhost -p 8001 "/admin?op=ping"

and see what the third response is.

If it still fails, configure "debug_options 22,9 20,5", purge the
cache.log and try the above three again. Hopefully the cache.log will be
left with a trace of what happend to non-cache the reply.
