johnm, I don't want to sound too harsh, but you registered half an hour ago, just to post a question. That's fine, you are not the first one to do so and we are happy to welcome you on board, but if you had looked at the site a little bit you would have found a couple of things:

• questions that get answers are usually much more precisely worded than yours, including a bit of code, whether you use CGI.pm, Apache & mod_perl, etc... all make it much more easy for people to answer.
• there is a nifty Search field right at the top of the page, SSI Cookies retrieves a long, long list of posts on the subject. Did you check them?

So I don't want you to think that we are a bunch of grumpy old misanthropes (most monks are much nicer than I am, just don't rub merlyn or tye the wrong way), but if you want this site to be useful for you I think you should spend a little time learning about it. It will make it much more enjoyable both for you and for the rest of the community.

Don't take it too personnaly though, I guess you are paying for the numerous newcomers that behaved the same way, but that's the long explanation for the short -- on your post.

And read those posts on SSI and Cookies...
