Different instant +messaging software are different endpoints, too. Server operator create configuration files, which describes how the +messages should be *routed* among distinct endpoints. This enables people from different Minecraft sub-server chats, even +different instant messaging platforms, together, in a tidy way. + +The routing is highly configurable. CrossLink does not care where the message comes from, +and where it will ultimately go. The forwarding process is entirely controlled and defined by the server operator. +Server operator combines **actions** like `filter by source`, `filter by content`, `replace by regexp`, `discard` +and `forward` into **rules**. Finite rules line up a routing table. CrossLink forward every message according to +the routing table. The combination of **actions** is versatile to help build a highly configurable +message forwarding system among Minecraft grouped servers and instant messaging platforms. + + +# Environment Requirement + +- Minecraft reverse proxy server： + - BungeeCord (not tested, compatible in theory) + - Waterfall (tested in `waterfall-1.18-470`) + - Velocity (tested in `velocity-3.1.1-98`) + +- Java Runtime： + - OpenJDK 17 (tested in `OpenJDK 64-Bit Server VM (build 17.0.1+12-LTS, mixed mode, sharing)`) + + +# Configuration + +1.
