Yes I had considered the popup method...it seems the easiest way to redirect the user to two places at once, so to speak.
The main problem with this is that I am on a free server (I will be moving up eventually, but I need to get going before I start paying), and there are a bunch of popup ads. I often use popup closers, and I'm sure other people will also (I even recommend some on the page because it's so annoying), so I would prefer not to rely on this.
Since posting, I've gotten time to do a little research, and I've found that apparently Java (which I know nothing about; though I can read and manipulate the code since it's similar to C++) can open URL connections without actually displaying them. I am attempting to pursue this route--when the Java applet is stopped by the browser (i.e. the page stops being displayed), it opens a URL connection to a Perl script in the background, while leaving the user happily on their way to the site they clicked.
Thank you for your reply, though!
(And for your correction on one of my previous posts--always good to make sure people are getting the best)
