Did a Browser have an ID?

[idealnet]

Hi @ all,
I have a site with following link:

<a target=_blank href..... >

This will open a new window and so I get a
main window(opener) and a child. Both display
my site.
Now, is there a way to get a browser or connection ID
as a PHP global var? I know only the HTTP_USER_AGENT
but with this I cannot diffenentiate trought the
opener and the child, but I have to know it in my script!

Is there another way to find out if the request is comming
in by the opener or the child?

Does anybody have an idea?

Regards,
id.

I would think you could pass a variable to your child window in the url and then put this into a hidden field on the page. That way you can check for the value of the hidden field to determine if it is the parent or child window.
