Creation of an Update Profile for Internet

      Disclosed is a method for determining optimum update times for
web sites and scheduling the updates.

      Many web sites do routine updates.  A site may, for example,
provide news that is updated at a certain time each day.

      Users can schedule automatic updates.  For example, a news
gathering program may be set to update at midnight each night.

      The problem is that users typically do not know the update
schedule for a site.  If, for example, a site updates at 8 a.m.  each
day, the user's browser is set to update at midnight, the user will
be looking at day old news each day.

      A technique is needed for users to determine when a site
updates.

      A solution is for the browser to automatically go out and check
sites indicated by the user to see if they have been updated.  The
browser can request a new copy of the page and compare it against a
cached copy.  If the new copy is the same as the old, it is
discarded.  If the new copy of the page has changed, the browser
records the time.

      The browser then builds a table of update times for each
site.  It can then go request updates each day right after the site
has refreshed.  This allows the user to always have the most current
data available.

      This technique can be used for any update schedule (e.g.,
daily, hourly, weekly, etc.).

      If the site has a time stamp, the download and compare can be
done...
