As I mentioned in my original post, the xmlhttp file access only works
within the same domain - security reasons. In the first example, the
same domain is assured by using the relative URL, in the second one, it
may not be (for example, you may need to add "www." to match the domain
of the page containing script; or it not work at all with the full
domain name - I have never tried it for the aformentioned reason)
