How to tell remote that javascript is running?

[Carl A. Schreiber]

Hi,

I want to download some html-pages that send something different if javascript 
is not running. So 
        use LWP::Simple;
        ..
        $got = get( $url );
does not work, because LWP::Simple does not tell the sever that javascript is 
running.

Is there a solution? Right now I don't need to run the javascript code I just 
want to act as it were possible.

Thanks in advance,
carl
