HTTP, HTTP/2, and gRPC Proxying

Linkerd can proxy all TCP connections, and will automatically enable advancedfeatures (including metrics, load balancing, retries, and more) for HTTP,HTTP/2, and gRPC connections. (SeeTCP Proxying and Protocol Detection for details of howthis detection happens).

Notes

• gRPC applications that use grpc-go must use grpc-go version 1.3 or later dueto a bug in earlier versions.
