Hi,
I have been playing around trying to build a 'perfect' shopping cart. A brief
as possible feature list: database driven, fully indexable by search engines,
and can operate without cookies.
I decided to use Apache's mod_rewrite to change a standard looking URL into
something php can use easily.
ex: http://www.mydomain.com/produce/carrots/spec1/94d0bb50cd.html
would become
http://www.mydomain.com/index.php?dept=produce&product=carrots&;
specials=spec1&PHPSESSID=94d0bb50cd
Now for the problem, when a search engine spiders this it will be including
the session id. Unless I do some kind of checking, I could end up with
multiple users having the same session id -- if they click into the site from
a search engine or a bookmark.
The best solution I have come up with is to add a timestamp variable inside
the URL. If the timestamp is more than 1 hour old -- reassign a new timestamp
and session id then build the page as specified by the other variables passed
to the script.
I was wondering if anyone knows of a more elegant solution for this problem.
thanks,
don
