Hi, [...] Further, I don't want any base tag at all. To disable Base Tags in Zope, I use the following hack in my standard_html_header: <HTML> <HEAD> <TITLE>foo</TITLE> <!--</HEAD>--> </HEAD> <BODY> Zope renders this as follows: <!-- <base href="http://localhost:9080/"> </HEAD>--> </HEAD> As you can see, the base tag is inserted in a place where the browser will ignore it.
