Webserv Project for 42 Seoul

This repository is for the 42 seoul project Webserv.
The objective of this project is to implement own http server.

Note

This repository contains only a portion of the code related to parsing the configuration file.
Due to the fact that I am not the sole author of the project, I cannot share the full codebase.
