A simple http server that can handle GET and POST request.
Written for computer network course.
GET method works like a normal HTTP server, but not setting index.* as the default index file.
As this server is just for the course, it maybe inefficient and insecure.
I used sendfile() to send the requested files, and mime type is judged by the extension name.
POST method is totally implemented for the lab requirements.
It will verify the username and password post to the /dopost.
make httpserver
./httpserver <public_dir>
