How to use unverified custom domains with Google App Engine <p>I need customers to be able to point their own custom domains to my GAE app.</p> <p>e.g. customersdomain.com -- CNAME --> myapp.com (which in turn points to myapp.appspot.com)</p> <p>I know that I can link a domain to my Google account and then use that domain to serve app engine, but this process does not scale and requires that I have direct access to the customer's domain register/DNS. The only other alternative is to force customers to sign up for Google Apps (why!).</p> <p>Almost all other PaaS make this process painless: </p> <ul> <li>In Heroku, I simply add the domain to a whitelist and the customer adds a CNAME record. </li> <li>In AWS, a single CNAME record pointing to the instance does the trick.</li> </ul> <p>Does anyone know of a workaround for this? Or am I just going to have to manually link hundreds of domains to my account?</p>
