A URL can contain all of the information in the individual flags as a single string rather than as separate pieces. I've mostly run into URLs pointing to Redis and this make those existing URLs easier to work with. This also introduces the -redis-insecure-tls flag which turns off TLS certificate hostname verification. We've chosen Heroku Redis for a recent project which requires TLS but, for reasons I don't know, they don't provide a certificate that is valid for the hostname. I also wasn't able to get the existing -redis-tls flag to work.
