In Fujian province, all foreign domains which aren't in white list are blocked.

This results that proxy server needs to use a fake sni in white list or ditch https.

This is actually supported by both the client and the server.

To use it in mobile clients you need to specify two domain names like that: fake-sni.com|domain.com where “fake-sni.com” is the domain thay will be in the SNI and “domain.com” is the domain in your TLS certificate (used to check the server’s authenticity)
