ProFTPD Developer's Guide: Server Internals

ProFTPD Version 1.2

Descriptions of ProFTPD Server Internals
This is a collection of descriptions of some of the internal mechanisms and workings of the core server, such as how it decides which handlers to call when, resolution of paths, etc etc. I decided to put these descriptions here for now, for lack of a better place for them; they are not exactly related to programming ProFTPD modules.

Please feel free to contribute explanations to this section. The source for ProFTPD is sadly lacking in in-source comments, and these descriptions aim to fill the gap for aspiring developers.
