I read the XY problem :). Thank you for your replies. Basically I want to know if a page is opened in a new window or not. If yes, then I want to do some processing before it is outputted on the screen. My pages are like: a.pl, b.pl, c.pl. If c.pl is opened from a link in a.pl in a new window, then during the processinf of c.pl i should come to know that so that i can append some extra stuff in c.pl output. That was the reason I was trying to find out if the page is in new window using Perl and not Javascript. So that if I can find out using Perl prior to outputting it, then I can modify it suitably. Now since you have said that I can modify using javascript, I can do the modifications in a.pl so that when c.pl is loaded in new window via a.pl I come to know about it. But what are the modifications required. Please guide me. Thank you very much, Anant
