+@section server_intro Introduction
+
+FreeRADIUS uses a thread pool to serve requests. Each request is processed
+synchronously, and processing passes through a series of stages, and a list
+of modules in each stage.
+
+The request is processed as follows
+
+- The radius packet is received by a listener - see listen.c
+- The radius packet is parsed and validated into a request - see ?
+- The request is processed - see process.c
+- The server passes through each authentication stage
+  - authorize
+  - if Proxy-To-Realm is set:
+    - pre-proxy
+    - send proxy request
+    - post-proxy
+  - else
+    - authenticate
+  - post-auth
+- Authentication stages are lists of modules - see modcall.c
