301 Redirect

mydomain.com to www.mydomain.com

In a posting last week [webmasterworld.com...]
GoogleGuy said:

For example, if you select [yourdomain.com...] as your root page, then if a spider tries to fetch [yourdomain.com...] (without the www), your web server should do a permanent (301) redirect to your root page at [yourdomain.com...]

I would like to find out the proper code to use with an .asp or any html site for this 301 redirect so that I can use www.mydomain.com when the bot comes to mydomain.com without the www in front. Can anyone point me in the right direction for this?

This is the asp code i use for my site. It handles querystrings too.

strServerName = Request.ServerVariables("SERVER_NAME")
strDomain = "www.example.com"
If Not strServerName = strDomain Then
strRedirectURL = "http://www.example.com" & Request.ServerVariables("URL")
If Request.ServerVariables("QUERY_STRING") <> "" Then 
strRedirectURL = strRedirectURL & "?" & Request.ServerVariables("QUERY_STRING")
End If
Response.Status = "301 Moved Permanently"
Response.addheader "Location", strRedirectURL
Response.End
End If

Thanks Jimmy but where do I put this in my site? Do I make a TXT file for it or does it go on the main index page before the metatags?

It goes in a file thepage.asp named as whatever page it is you want to redirect from.

For Windows servers also look at ISAPI rewrite and IIS rewrite.

Sidenote. With Apache it is so much easier: three lines in the .htaccess file, or a line of PHP code in visible page file.
