The URI which in your example is /code.html can be anything, including something like m.html. In that case which would be the first 2 letters? Or, the URI can be something like m-like.html. In this case the first 2 letters will be "m-" or "ml"? A good regular expression should work in all situations so it is important to know what is the desired result, and not to asume that there won't be any links like "/.html" or something worse. Teddy
