The gRPC proxy module. The module allows passing requests to upstream gRPC servers. The module is built by default as long as HTTP/2 support is compiled in. Example configuration: grpc_pass 127.0.0.1:9000; Alternatively, the "grpc://" scheme can be used: grpc_pass grpc://127.0.0.1:9000; Keepalive support is available via the upstream keepalive module. Note that keepalive connections won't currently work with grpc-go as it fails to handle SETTINGS_HEADER_TABLE_SIZE. To use with SSL: grpc_pass grpcs://127.0.0.1:9000; SSL connections use ALPN "h2" when available. At least grpc-go works fine without ALPN, so if ALPN is not available we just establish a connection without it. Tested with grpc-c++ and grpc-go.
