问题
I want my app engine service to speak with a separate service that I manage. I want to be able to install my self signed certificate on both ends. Is it possible to have app engine speak to this instance over SSL?
回答1:
Yes. App Engine doesn't currently verify certificates for SSL sites over urlfetch, so it will accept self-signed certificates just fine.
