Checking Error Pages ahead...

[duniyadnd]

Suppose I have a bunch of links pointed to a particular website which has plenty of articles. However, after a point of time, they change the URL directory its posted in, so I get an error page, with the same URL I pointed to. Is there a way of ensuring that I can check the page i'm going to ahead of time, so I can choose which link I'm going to?

eg. I have a link:

http://www.coolsite.com/newstuff/article1.php

but they move this site to:

http://www.coolsite.com/oldstuff/article1.php

and I see an error page pointed at http://www.coolsite.com/newstuff/article1.php

Is there a way of checking if there is an error page and if there is, just to to the next option which is "oldstuff"?

Thanks
