Sample User-Agent Log

The following listing is philosophe.com’s user-agent log (from April ’99), reformatted
into a simple alphabetical and hierarchical sorting and with all multiple entries removed.

As you can see, even for such a small site as this, there are a bewildering variety
of browsers and browser references recorded. You can imagine the increased range
of browsers that might hit a publicized and advertised commerce site.
