SSL on Custom Domains for AppEngine and Other Cloud Services

The text discusses an issue with enabling SSL on Google AppEngine using custom domains. It explains that managing SSL certificates in cloud environments is challenging, as they are usually tied to a specific domain and IP address. The author mentions that many cloud providers do not support SSL or require users to use their subdomains for SSL-enabled connections. To solve this problem, CloudFlare introduced a new feature called Host Override Header, which allows developers to enable SSL on custom domains hosted on AppEngine. This solution helps maintain session consistency between HTTP and HTTPS connections and offers potential opportunities beyond SSL support.
