those are different urls and i've seen examples of both or the wrong one being indexed. requests for the second url should be redirected to the first url using a 301 status code. also your default directory index document setting should be configured to use index.html.

Never link to named index file.
Link to href="/" or to href="/folder/"

Will Google see these two urls as the same location or different?
