Couldn't get your link to work, maahey. With a bit of digging around on aoidoi though I did find the reference. The address in the address bar looked exactly the same as what you've got, so I don't know why.

Later edit. Got it. Your full stop got caught up in the address. The link should read http://www.aoidoi.org/articles/meter/intro.php .
As for hemiepes, I haven't checked this, but he seems to be saying that the word is made up of hemi = half + ep = epic + es = adjectival ending.
