We have rewritten our website using the Xara Web Designer Premium and when we replace our legacy site with the Xara version we see the following issue:

-) we point the Microsoft IIS to the legacy folder containing our index.htm file
-) we open a browser on another system and enter www.mydomain.com
-) all works well
-) we delete all of the files in the legacy folder and replace them with the files exported by Xara
-) we open a browser on another system and enter www.mydomain.com
-) the URL immediately goes to http://www.mydomain.com/www.mydomain...w.mydomain.com....
-) this recursion ends with the browser issuing an error
-) when we copy the legacy files back, the site works again

We are sure there is a basic issues we are overlooking, any help would be appreciated.
