The URL can point to a local file using the form:
file:///C|/dir/subdir/file.ext
The URL can also be a remote URL where the page is
cached locally:
http://www.place.org/dir/subdir/file.html
Please note that you may have to replace '\' by '/' and 'C:\' by 'file:///C|/' in your own pages, which makes them portable to the Web.
http://www.place.org/dir/file.html C:\CACHE\FILE.HTM
Any links to the remote URL will open the local file.
For example, follow this link to pretend these pages are hosted on the Knots Web site
