You can do that with.... javascript...

I'm thinking that a url with a meta/redirect of a couple of seconds and
a javascript redirect with a shorter timeout to different URLs will do
the trick.

Display a message to the client telling them to turn on javascripa ( or
get a js enabled client), or you could write your scripts in such way
that javascript is optional.

All of this is offcourse OT in a php group since you are doing
clientside stuff.

thxs for information but i could not get what actually you want to say.
so please if you can write in some detail then i will be very thankful
to you.

On your main page write the following:

<meta name="refresh" http-equiv="5;URL=nojavascript.php" />
<script language="javascript" type="text/javascript">
window.location = "javascript.php";
</script>

i have written this code and the page can not be displayed is message
but tell me how web server will know that javascript is not supported
on this client.

The server doesn't know untill you tell it (like in a session).

Annoying and not userfriendly.
