what I am trying to do is block an ip after they go to my website, soonce a person comes across my site has a look around or even just onepage, and then leaves they are blocked and cannot come back a secondtime. so basically A log would be made with all the user ip's that hitmy website that become blocked. I have tried to have a look around onthe web but haven't had much luck.

I am not a programmer and usually just try to pick it up as I go along, any help would be much appreciated.

There is a reason for that!

It's not something that anyone who runs a site properly would want to do! Return visitors are the lifeblood of just about every single site in existence.

Apart from the fact that it is utterly impossible with javascript and totally impractical with server side code.
