[Zope] anyone? Help getting the correct URL from absolute_url or portal_url

I found no reference to base href in the document. I don't set it and I 
don't see that ZOPE/CMF sets it either.

here's the ZPT code that's generating the urls for the items

   <li tal:repeat="item items">
    <a href="item_url" tal:attributes="href item/absolute_url"><img
      align="middle" border="0"
      tal:attributes="src   string:${item/portal_url}/${item/getIcon};
                      alt   string:${item/Type};
                      title string:${item/Type}"></a>
    <a href="item_url" tal:attributes="href item/absolute_url;
                                       title item/Description"
       tal:content="item/Title"> Title </a>

both absolute_url and portal_url when called within the frameset appear to 
get a reference to the parent frameset's host instead of the document's 
host. Are there other mechanisms in place to get the host name:port for a
