YServer is simple and easily expandable at the source code level. It supports multiple users, requests for file resources under a public directory root (with the request http://<server IP>/<resource path>), the HTTP methods GET and POST, MIME types, and file uploading (with the request http://<server IP>/upload). YServer reads initialization settings at startup from a file. New custom functionality can be easily added by overriding a couple of methods. This allows to extend YServer in a way similar to CGI scripts. YServer has served as the base class in the development of a number of research prototypes.
Changes to the initalisation file (server.ini) should not be made while YServer is running, and will take effect the next time YServer will run. The server.ini initialisation file is as follows:
