Well, I'm just this kind of sysadmin, and I'm fed up of persuading
users to turn their cookies on, because many of them don't read that
cookies must work on our site, others don't know what the cookies are
and don't know how to turn it on back. And sometimes browsers f@#k up and
don't handle cookies properly (e.g. Opera6.01 and IE6 in some
installations). And sometimes proxies cache cookies with other headers
and send them to everybody using those proxies. I have the situation
when the session just go away for SOME people, in SOME circumstances,
and I have it now. And I understand that we live in not such a perfect world
where things are beyond our control in spite of rich and available
specifications. So, don't expect that this is so uncommon - such
things will last forever.
I just sat down and calculated a bit. Let us have the stats of cookie
usage - the stats are available everywhere. In Russia it is common
that the rate of cookie-disabled browsers is from 3 to 5 per cent. So,
we have a risk that 5 per sent of users won't be able to use our
service if we enforce cookie usage. Then, what is the probability of
changing client's IP during the session. I don't think it would be
more then 30% (in the worst case). So, we can lower the risk by 2/3
without a loss (since we enforced cookies on everybody before). Does
it matter? I think, yes, I'll have only third of those people who may
experience problems with my site.
