Basic HTML behaviour is your culprit. I bet if you look at the source
you'll find it looks like::

<a href="www.foo.com">www.foo.com</a>

Problem is this looks to the web browser like an address relative to the
current URL path. You must always have a protocol in an external link.
So you can fix the source of the data or say::

<a tal:attributes="href string:http://${rdata/webpage}"
tal:content="rdata/webpage">webpage</a>

That should do the trick.
