[S] Videos at IMDb

[zoltan]

I think I just had one of those light bulb moments and finally get it. As I learned in post 2 of this thread, once an address is matched in a list, it can't be matched again. That concept had gotten hazily merged in my mind with the idea of 2 potential addresses from the same domain separated by an OR. Because of that, I was thinking that matching the video from imdb.com would (because of the OR) prevent the js links from imdb from being matched down the page.

In other words, I was thinking that it ran the whole page through the exception expression in one instance. But the new understanding is that it looks for matches one at a time. So even if the doubleclick part matched, it wouldn't matter because when it parsed the js links URL, it would be a fresh instance of checking the expression for a match. The doubleclick match would be irrelevant. Of course, by this understanding it's amost impossible to think of a situation where the OR would matter.

Hopefully this isn't totally off base.
