Squid does not automatically check for update pages, but you can do this
with wget in a cron job.

You can put a list of urls in a file and then use the
'--input-file=file' or '-i file' option with wget to. For example
http://www.kernel.org

Other options to look at:

-r - recursive
--timestamping
-p or --page-requisites
-nd or --no-directories - Do not create a hierarchy of directories when
retrieving recursively
-nH or --no-host-directories
-q - quiet download
--tries=number - Set retries number

man wget shows all the options.

Then set http_proxy = http://1.2.3.4:port_num/ in wgetrc to whatever
your squid server is and run wget from cron job whenever you want during
the day. Squid will get updated.

I am not an expert on wget, but I do use it to load/update Squid.
