Using "www" for subdomain of Google Apps

Due to temination of Google Page Creator, I moved hosting of static files to Google App Engine as I wrote the following article.

• Migrating static contents from Page Creator to App Engine

When I moved to App Engine, I set up “www” to the subdomain for GAE. And I disable Page Creator on my Google Apps Account. It has worked as expected… until Google migrate page creator contents to Google Sites last December.

Google revived my Page Creator contens in Google Sites, and assigned “www” as the subdomain of Google Apps, that prevented access to my GAE contents. Moreover, even though I removed “www” from web address mapping of Sites, I couldn’t resolve the problem to access to my GAE contens with subdomain “www’.

Now I could fix the problem lately, according to the following help topic (Japanese) of Google Apps, here is the notes.

• Google Sites で作成したサイトの URL に、サブドメイン www が割り当てられない

In short, to use “www” as submain of Google Apps, assign “www” to Start Page, and then change subdomain of Start Page, asign “www” to another Apps.

Here is the exact steps to assign “www” to GAE in my case.

1. Remove “www” from Google Sites addresss mapping (removed page creator contents from Sites too)
2. Remove “www” from my DNS settings (You might not need this step and step 4)
3. Assign “www” to Start Page of my Google Apps
4. Set up “www” to CNAME record (points to “ghs.google.com.”)
5. Change subdomain of Start Page (e.g., “start” or something)
6. Assign “www” to GAE (web address setting)
