Or write a simple Perl script with "tail -f" functionality that will read
the [standard] log file and pipe the lines to your external logger.

The script solution avoids this problem since a script can preserve the last
position read (and piped to the logger). Should script die, it can be
restarted from the saved position. Rotation of logs is not a big problem
either since it is easy to detect in the script (file size gets smaller).

In short, you get a more robust solution, but you pay with disk space and
your time to write the script.

We used to have a similar script here to restart beta Squid versions when a
particular string appears in the cache.log. We do not use it now though.
