Forwarding Naked Domains for Appengine with Apache Posted on August 26, 2009 by Dave Fowler
Google Appengine currently does not allow configuration of naked domains. Meaning, if you're building something on Appengine you'll have to settle for a URL like http://www.mysite.com or http://whatever.mysite.com and you will not be able to use http://mysite.com.
Its not so bad in most cases, but not having http://mysite.com isn't going to stop people from trying to go there. So its important to set up some sort of device to forward the naked domain to the www.
Unfortunately you're going to need a server and for this example it will need to be running Apache2. The redirect is handled by placing the following line in an apache config file (/apache2/httpd.conf).
Redirect permanent / http://www.mysite.com/Where http://www.mysite.com is the example site being hosted on Appengine.
Or, if your apache server is hosting other apps and domains you'll need to set up the redirect in a VirtualHost as shown here.
<VirtualHost *:80>
ServerName mysite.com
Redirect permanent / http://www.mysite.com/
</VirtualHost>Note that the 'permanent' parameter in the Redirect command enforces a 301 or permanent redirect. You can choose other forms of redirect by replacing the 'permanent' with either the redirect number (ie 302) or the keywords from the following table I've shamelessly copied from here.
HTTP Code Status Description
301
permanent
The resource has permanently moved
302
temp
The resource has temporarily moved
303
seeother
The resource has been replaced and refer to new resource
305
UseProxy
Use proxy to access site
307
Temp
The resource has temporarily moved
410
Tegone
The resource has permanently removed
Finally set your DNS to point the base domain to this apache server and in a few hours it should be permanently re-directing http://mysite.com/ to http://www.mysite.com/.
