In general, if you want to load in a web page, you will need to precede
the URL with http:// and set the Data Source Type to "Text or HTML
files" on the URL chooser. This chooser is generaly for loading in a
particular dataset, not to display web pages, although that can be
done with the following caveat. The display that shows web pages only
displays basic HTML and does not support JavaScript or Frames. So, if
you try to load in the Unidata home page, it will not be well formatted.
