Re: WWWVL: gathering stats (usage)

Great idea!

Easy!

For info.cern.ch, we really need to process day per day...

Results are, from December 2 to December 6:
- for the top page Overview.html
     40 000 to 45 000 requests on week days
     20 000 to 25 000 requests on week-ends

- for its "summary" Overview2.html
     1 500 to 2 500 requests per day

I don't mind wether we use a stat file, or comments inside the file.
But I remember we had a previous discussion on this:

This isn't an issue for me: both solutions are easy to implement in perl.

An inclusion to the existing file would be:
<!-- Usage: 350 -->
<!-- Links: 765 -->
<!-- Cited: interactions, July 1994, p 10 -->
