The URL Scraper provider gets content from configured URIs. Before sending these URIs to the browser, it expands all relative URIs to absolute URIs.
For example, if a user is trying to access a site as:
<a href="../mypage.html">
Rewriter translates this to:
<a href="http://yahoo.com/mypage.html">
where http://yahoo.com/test/ is the base URL of the page.
