Here is a 301 redirect XSLT file I am using that essentially does a 301 redirect.  Create a macro from this with a parameter called redirectUrl

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
  version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xmlns:msxml="urn:schemas-microsoft-com:xslt"
  xmlns:msxsl="urn:schemas-microsoft-com:xslt"
  xmlns:redir="http://www.umbraco.org/redir"
  xmlns:umbraco.library="urn:umbraco.library" 
  exclude-result-prefixes="msxsl msxml redir umbraco.library">
   
  <xsl:output method="xml" omit-xml-declaration="yes" />
    
  <xsl:param name="currentPage"/>
  
  <xsl:template match="/">
    <xsl:variable name="redirectUrl" select="/macro/redirectUrl" />  
    <xsl:if test="$redirectUrl != ''">
      <xsl:value-of select="redir:Redirect($redirectUrl)" />
    </xsl:if>
  </xsl:template>
  
  <msxsl:script implements-prefix="redir" language="C#">
    <msxml:assembly name="System.Web" />
    <msxml:using namespace="System.Web" />
    <![CDATA[
      /// <summary>
      /// Redirects a string site to a 301 Redirect
      /// </summary>
      /// <param name="url">String to redirect page to (usually passed via macro parameter)</param>
      /// <returns>String.Empty</returns>  
      public string Redirect(string url){
        System.Web.HttpContext.Current.Response.Status = "301 Moved Permanently";
        System.Web.HttpContext.Current.Response.AddHeader("Location", url.ToString());
        return String.Empty;
      }
    ]]>
  </msxsl:script>
</xsl:stylesheet>

Create a document type for your new 301 Redirects.  Inside the doctype create a textstring property and inside the template of the doctype add:

<umbraco:Macro redirectUrl="[#PropertyAliasHere]" Alias="MacroAliasHere" runat="server">umbraco:Macro>

Hi,

Thanks for your help.

When you wrote "Create a document type for your new 301 Redirects" Do you mean that I have to open pages under the site content node for each old url page which I redirect?

is working on a reply...
