Guide on how to use various public services for meek
You only need a reflector-like thing when the CDN-like thing doesn't let you point to arbitrary domains. Amazon CloudFront lets you point to any domain, so the reflector is the CDN itself. Google only lets you point to a Google domain, so to get around that you run an app on App Engine. Azure also only allows you to point to an Azure domain, so you use the PHP or WSGI code.
It would be nice to collect this information into a document in meek.git for others.
