Logging System - SessionID OK?

[StrangerInBeijing]

Hi,

I'm designing a new logging system for my site.
Hellova lot of stuff can be logged...I mean, there's over 21,000 news articles alone!
Anyhow, a user might not be logged in, so I cannot see who it is.
I was thinking that if I can log the user as he click on links, even though I donit know who it is, I still would like to see what he tried to do, or what "path" he took.

So my question is: Is a sessionid unique to the user's session? If a user open the main page, and jump between pages, will the sessionid remain the same (unless the session times out of course)

Any advice, ideas will be welcome. The current logging system implemented by the previous devleoper became obsolete and inefficient, now that we implemented new services.

Thanks in advance

Yes, SessionIDs are statistically unique. Allow, in your code, for the non-existence of SessionIDs as well, as some crawlers/browsers may not work with one.
