I moved a file on my site: http://www.luxuryspa.se/massage.html to http://www.luxuryspa.se/spa/massage.html.
Ooops... people had published links to the old adress and suddenly they'd get a 404 - File or directory not found Error. It showed up in Googles Webmaster Tools.
So I googled the problem and there was little advice on how to handle the problem with html-files on IIS. This is how you do it:
- Create a file with the name you'd like to redirect from. In my case massage.html and save it in the old location (I just wrote "301 Redirect to http://www.luxuryspa.se/spa/massage.html" in the file so I know what it is)
- Start the IIS Manager and go to the directory for your old location. Select the newly created file and right click it. Choose Switch to features view.
- Now you can see the file to the left and it is selected. So go ahead and double click HTTP Redirect and fill out the form. For me: http://www.luxuryspa.se/spa/massage.html and status code 301.
