Redirect 301 cheat sheet

Inspired by Jesper Åström’s series of redirect articles, and because taking care of redirects is important, I thought I’d share the cheat sheet I keep in my personal wiki. Similar information is available elsewhere, but it’s worth repeating.

As a LAMP-boy, some of these redirect methods (such as coldfusion and IIS) I haven’t used or checked recently – so double check that they are correct before doing any serious redirect work!

301 redirect with.htaccess for a single URL

RewriteEngine On
Redirect 301 /old/old.html http://new-url.com/new.html

IIS Redirect

1. In internet services manager, right click on the file or folder you wish to redirect
2. Select the radio titled “a redirection to a URL”.
3. Enter the redirection page
4. Check “The exact url entered above” and the “A permanent redirection for this resource”
5. Click on ‘Apply’

<.cfheader statuscode="301" statustext="Moved permanently">
<.cfheader name="Location" value="http://new-url.com">
