Crate rws_proxy 

The proxy and operations layer of rust-web-server: reverse proxy, config-driven routes, load balancing, L4 and WebSocket proxies, the admin API, cluster sync, fleet pull, WAF, LLM and A2A gateways, FastCGI, traffic insights.

Internal to rust-web-server, released with it at the same version: use these through the rust_web_server paths, which stay stable; this crate’s own layout may change in any release. See spec/WORKSPACE_SPLIT.md.

Modules
