Is there any way  to know any URL is currently displayed in Netscape browser? Suppose http://www.xyz.com is running in Netscape browser, do i have any way to know the URL name whatever is running currenlty. One more flexibility is there that the URL name will be known to me before searching.

if you get window.location, you can get the currently displayed URL in any browser.  From where do you want to know the currently displayed URL ?

try this:
<script>
var img=new Image();
img.src= "http://yourserver.com/path/to/script.php?browserLocation="+top.location.href;

This code should work:
 
<script language="javascript">
document.writeln(document.location);
</script>

If you find out the referrer of your page and compare it with your current page(to see if the refresh button has been hit)
just do
<?
if ($_SERVER['HTTP_REFERER'] == 'http://'.$_SERVER['SERVER_NAME'].$_SERVER['SCRIPT_URI'])
{
  echo 'you hit refresh';
}

?>

Probably I was clear in question. suppose on one Netscape window "www.xyz.com" is dispalyed/running and if I open one more new window and try to open same "www.xyz.com" now in this case in second window i wanted to display like www.xyz.com is opened in another window.

Thanx your earlier comments and sorry for making confused. please let me know can we solve this problem.

There is no way of telling how many windows are opened by netscape to view your site because of security reasons

if the 2nd was opened by your page then you could use javascript to get the url of the parent window.

var url = window.opener.location.href;

but if you mean when you use the broswer and go file->new->window. thats a different story.

if the point is that u do not want a user to be able to open your application twice, there could be one way.
if u use sessions in php, you can make a javascript which at loging time either open a hidden window or set a global variable "session_is_opened=1;".
then, when a page is loaded, if the session already exists but the variable is not set, or the hidden window can't beaccessed, then your user has opened another browser window and pasted the url (so the session is kept but the browser-depending operation is not) which is what you want to detect ???
