If you set anchors in html content and additional put some HTML comments, under IE7 the hrefs will be placed as absolute.
For example the following HTML:
<div id="htmlcontent">
<div>
<!-- comment beginning -->
<a href="/relativePath/ToALink">
<img alt="" src="relativePath/ToMyImage/image.gif" />
</a>
</div>
<!-- /another ending comment -->
</div>
Will be transformed to this one:
<DIV id=htmlcontent>
<DIV><!-- comment beginning --><A href="http://localhost:52771/relativePath/ToALink"><IMG alt="" src="http://localhost:52771/relativePath/ToMyImage/image.gif"> </A></DIV><!-- /another ending comment --></DIV>
