well the answer is you other mail + the squid.conf
"Without the cache_peer I can not get to any sties at all. All
internet (well, http and https) traffic on our network must go through
the parent proxy, either directly or through a local child proxy."

the proxy tries to connect the direct upstream server to get access
because you dont have an explicit "never_direct allow all" acl defined.
so post and other requests that requires direct access will then tried
to be served by accessing the origin server.
you must be explicit with cache_peer acl.
replace:
##
cache_peer 10.55.240.250 parent 3128 3130 no-query default login=PASS
##
with
##
cache_peer 10.55.240.250 parent 3128 3130 no-query default login=PASS
name=upstream
cache_peer_access upstream allow all
never_direct allow all
##

this will allow and will force all traffic through the upstream proxy
server.

Good luck,
Eliezer
