This little component will retrieve the contents of another URL.
So, in your template:

  <Include url="http://raa.ruby-lang.org/project/iowa" oid="fetch_raa"/>

Would cause this component to fetch the Iowa page from RAA and insert
its contents into the response from your template.

This is a simple component, but could easily be expanded to accept
additional parameters such as number of times to attempt a URL or a
fallback response page in case the desired URL can't be reached or
content filtering, for example.
