Be careful when you use something like index.php?showpage=news.php and include() that $showpage
file.
If a malicious user would call your script as index.php?showpage=http://some.server/script.php it would include that script
and run it in *your* script's scope. That means it can read all files and variables your
webserver has access to!
This is not true as http://some.server/script.php will
only be executed by the server http://some.server and output that
in the HTML form to the first server with index.php.
