  Did you do a restart or reconfigure? They're not the same. The
safest way to change full configuration is to shutdown and restart.

  A couple people (including myself) have found that squid can engage
in bizarre behavior relating to process owner, permissions, etc., if
you run squid as a user which can not read its own squid.conf file and
then use the "reconfigure" signal to it.

  In place of running squid as nobody/nogroup, you might find it easier
to manage if you create a squid user with its own user and group. Then
you can either launch it from root if you need to keep squid with a low
port number, or (preferred) always start squid as the squid user and
squid group so it need not change euid/egid.

  (One indirect moral: when you first start introducing a proxy to your
testers or users, announce it on a high port number if possible.)
