In v4 redirecting of pages can be done easily using inline
ASP.NET scripting in the header part of the (mater) page.
In this example the redirect-function is inserted in a
slave-template of the MainMaster template using the header
placeholder id MainMasterHeadContentPlaceHolder
<asp:content ContentPlaceHolderId="MainMasterHeadContentPlaceHolder" runat="server">
<% Response.Redirect("/umbraco-workbench.aspx"); %>
</asp:content>
