This is not what "transparent proxy" means. That term means Squid is
transparent to the web server.
I guess you have a NAT interception proxy. Your mention of PF later
supports this guess.

  How close is the site?
  is it an internal or external site?
  is the error generated by your squid or something else outside?
  what is the exact access.log lines for the error and the working?
  what is the squid config?
  where does Squid gets its DNS from?
  what does that resolver report as the sites IP(s)?


Please be using
   Current Stable Squid 2.7.STABLE9 or 3.1.9
   Beta testers wanted for
