If you activate the function "Use variables", you can use variables on any sub-page and in all layout settings.
For Example, if you were to write on your website:
"Hello visitor, your IP is [ip]"
your visitor will see something like this:
"Hello visitor, your IP is 119.63.136.125"
You can use following variables:
[ip] displays the IP address of your visitor.
[browser] displays which internet browser your visitor is using.
[url] displays the url of the sub-page your visitor is currently viewing.
[subpage] displays the title of the sub-page your visitor is currently viewing.
[urlasinput] displays the url of the page your visitor is currently viewing in an input box. Useful, for example, for websites using frame redirections.
[hits] displays how many hits your website has had today.
[visits] displays how many unique visitors your website has had today.
