do SEs see these URLs differently?

Silly question, but I haven't seen anything on it

Do SE's veiw [example.com...] differently from [example.com...] . It's a silly question, but I wasn't sure. I know they see [example.com?session=1234...] differently, but what about just a slash?

Google listings appear with the slash at the end so I would say it doesn't matter.

Let me complicate the question somewhat, how about these URLs:

1) [example.com...]

and

2) [example.com...]

I know that most web servers would (or even should) issue 301 redirect for every request for "PossibleDirectory" to "PossibleDirectory/" so long as there is no matching filename available.

People could use both versions to link to the same page, but technically two strings will not be exact match. One would never be sure if its a directory request in a URL without slash at the end until trying to request URL from webserver. So, in this case it appears to be logical for search engines to ignore all trailing /'s.

Thoughts?
