Check the path that your web server is using. Also, you should be able to set the defualt document that gets served if none is specified…(which isn’t always index.html)…
Sorry, other posters seem to get what you are doing but I don’t. Are you trying to figure out how to do something with your own web site, or figure out why some site you are accessing is behaving differently than you expect?
If the latter, it is very common that when you type
www dot MySite dot com
you get a main page that does a redirect to another file. I am not at all familiar with CMS so not sure how that may or may not play into it.
