Exactly. You are asking Squid to predict what the future response status
code will be. Squid cannot predict the future. At pre-cache REQMOD time,
the response does not exist yet. Moreover, if an adapter changes the
request, the response may be different (and may even come from the
adapter itself!).

You may want to draw a diagram of what Squid does when processing a
typical miss request. The sketch below simplifies things a little and
omits message body processing, but can be used as a starting point:

  * receive virgin request headers from the client
  * start request adaptation
  * send adapted request headers to the next hop
  * receive virgin response headers from the next hop
  * start response adaptation
  * send adapted response headers to the client

I recommend testing with an "all" ACL. When everything else works,
replace it with a more selective ACL (if such an ACL exists).

HTH,

Alex.
P.S. You do not need the adaptation_service_set line.
