Domain Mapping with Google

If your site is created through the Google App Engine, only the site administrator can map a site to a custom URL through the Google App Engine’s control pane. To do that:

2)      Select the tab ‘Web Address Mapping’ from the Site Settings section
3)      Click on ‘Add a New Web Address’ and enter the name of the site to be mapped to the new URL
4)      Add the Sub URL to be mapped to the site in the Web Address section
5)      Finally, select ‘Add Mapping’ which will provide the necessary information to proceed with the mapping.
Note that it will take up to 24 hours for the changes to apply to your site.
