I'm unsure about this.

I have created /workng/subdir/page.aspx (/ = webroot) [1], which calls the
same ascx as before (from /a/ssi/footer.ascx).

No problems. See http://www.hostmono.net/working/subdir/server.aspx for


<%@ Page Language="C#" trace="true" debug="true" %>
<%@ Register TagPrefix="UserControl" TagName="Footer"
Src="/a/ssi/footer.ascx" %>
<title>HostMono Blah</title>
<style type="text/css" media="all">
        @import url(a/c/hostmono.css);
        <div id="assy">
        <UserControl:Footer id="myFooter" runat="Server" />
