+# CSCI 4061: Project 4
+
+The fourth project in CSCI 4061: Intro to Operating Systems.

+
+The purpose of this program is to create a multi-threaded web server by using POSIX threads. In this project, we wrote the backend using POSIX sockets.
+
+In order to run this program, compile with the included makefile (run ```make``` in the directory with no additional arguments). After that, run ```./web_server``` with the following additional arguments seperated by only a space (with no quotes or brackets):
+[Port used (between 1025 and 65535)] [Web server directory] [Number of dispatch threads] [Number of worker threads] [Maximum worker queue length] [NOT IMPLEMENTED (Use 0)] [Maximum cache length]
+
+
+#### Program structure
+
+```init():```
+Binds a port that the server can use to communicate with the outside world.
+
+```accept_connection():```
+Makes a one-time use socket for the connection.
+
+```get_request()```
+Takes the HTTP request and translates it to a file path that the server can use.
+
+```return_result()```
+Formats the return to the HTTP protocol and returns the successful request back to the client.
+
+```return_error()```
+Formats the return to the HTTP protocol and returns the unsuccessful request back to the client.
+
+
+#### Team Contributions:
+
+Matt wrote init(), return_result(), and return_error(). Andrea wrote accept_connection() and get_request().
