Ok the title is a bit ambiguous, but I really don't know the word to sum it up.
I want to make a site that use www.something.com/bla
Instead of www.something.com/bla.html
I know this can be achieved by making a new directory called "bla" and then putting a .index.html inside that directory, but I've seen on some sites where the index.html doesn't exist.
I did try searching for an answer but I just didn't really know what to search for or how you'd describe it. I know I've seen a thread about it before, anyone got any ideas?
Edit: Better example - http://en.wikipedia.org/wiki/Hello - No extension there. If you try adding /index.html or .php or .asp etc etc the file still isn't found. This should clarify what I want to find out.
