You don't need to HUP squid! :-) Just wait up to five minutes.

In client_side.c there is a variable called CHECK_PROXY_FILE_TIME.

It is by default, measured in seconds and set to 300.

Every CHECK_PROXY_FILE_TIME seconds, squid checks the cache modifiction
time, if the file has been modified, it will be reloaded.

The reason behind this is because squid assumes that there is an external
place where people [students] can change their password. In fact if the
user types in a bogus password, they will get an error page refering to a
generic chpasswd.cgi program.
