"MiniShare is meant to serve anyone who has the need to share files to anyone, doesn't have a place to store the files on the web, and does not want or simply does not have the skill and possibility to set up and maintain a complete HTTP-server software such as Apache. The application is meant to be as easy to use as any common software most users use daily. However, this doesn't mean experienced users can't find it useful."
The program is unable to manage some user's requests. In fact it waits at the end of each request at least two newlines. So if you send to the webserver a GET or an HEAD request with no or at most one newline, the webserver will crash.
