or please give me some tips for Canonical Hostname Redirect (non-www to www)

IIS - asp

 

That is asp code so make sure you page has a .asp extension (not .html or .php or .aspx or anything else).

 

thank you but also the file extension "asp"

i get 500 internal server error

 

Try this (change to your file extension and domain name).

RewriteEngine On
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.htm\ HTTP/
RewriteRule ^index\.htm$ http://[B]www.xxxxx.com/[/B] [R=301,L]
RewriteBase /
RewriteCond %{HTTP_HOST} ^xxxxx.com$
RewriteRule ^(.*)$ http://[B]www.xxxxx.com[/B]/$1 [R=301,L]

 

than kyou friend but your code is not for IIS - asp

 

i tried like that;

<%
If InStr(Request.ServerVariables("xxxxxxxxxxx.com"),"www") = 0 Then
Response.Status="301 Moved Permanently"
Response.AddHeader "Location","http://www."
& Request.ServerVariables("xxxxxxxxxxx.com")
& Request.ServerVariables("asp")
End if
%>

finanly not worked

 

500 error almost always puts the error into the webserver's error logs. The error even says that it's doing so. Did you check to see what the issue is?

 

try to add the following code and test.

 

thank you for considiration.. but your code isnt Canonical Hostname Redirect (non-www to www)
