www.domain.com//page.html (2 or more)
Same content, different full URL. So I noticed that if you type in any domain with extra trailing /'s, those also come up. My question is if this should be a cause for concern if Google is showing multiple instances in the supplemental results. Is it possible they're viewing those pages as duplicate content? I don't have separate pages on my server with those extra / occurrences - just the one normal file. I'm sure others have heard of or seen this. Please enlighten me, and if you know of a fix, that'd be great too. Thanks!

Yes, I think it's safe to say that's it exactly. And they invariably pick the bogus "double slash" url to throw into suplemental, filtering it out of the regular results because it IS an exact duplicate. Now, if the double-slash url show in the regular SERP for some reason, then I might begin to worry.
Let me share with you my experience. At the time of Jagger in Oct/Nov 05, internal pages of my sites got dumped by Google, and that was the very first time that I noticed Googlebot crawling double slashes. The urls with double slashes went into supplemental; I then put 301 redirect around the beginning of Nov 05...the correct internal urls with only 1 slash did not return to rank again until Feb 06 (very slow return and not all). I'm not sure whether the occurrence of double slashes have any direct adverse effect, but its appearance is not a good sign.
I found the problem inside a configuration.php file where the base url or "live site" had a single slash at the end. Removal of that single slash in the configuration.php file cured the double slash problem sitewide.
No clue if having the double slashes hurts or not, they just don't look or feel right.
I am trying to come up with an included asp redirect at the top of each to deal with it, no luck so far. I have one that works fine for non www to www. Anyone had any luck coding one yet?
