Description
Title: JSON-RPC over HTTP support
Description:
JSON-RPC is a light-weight, transport-agnostic remote procedure call (RPC) protocol. The most common transport protocols are HTTP and WebSockets, and sometimes TCP and Unix domain sockets.
JSON-RPC is commonly used to provide remote access to management interfaces. It is particularly prevalent with cryptocurrency P2P clients, being the primary access method for the majority of projects.
A common use-case of an Envoy JSON-RPC filter is access control. For example, the ext_authz module could be used to limit access to harmless read-only methods to lesser privileged users, while allowing admins full control.
