Multithreaded HTTP Server with Logging

• This program is a multitreaded HTTP server which is able to parse GET, HEAD, and PUT requests from multiple clients in parallel. In addition, the server is able to, concurrently, log all requests and perform a health check of the server.
• Multithreading was implemented using a stack and a dispatch worker model in which one thread is allocated as the dispatch handing off requests and the others are workers receiving requests from the dispatch.
• Logging was done to a single file and to prevent data hazards, a global byte offset was calculated to prevent threads from overwriting another thread's logging data. All data hazards (RAW,WAR,WAW) have been accounted for.

Usage:

When you run httpserver you must specify the port, whether you would like to enable logging, and the number of threads. Logging and number of threads are optional parameters.
-l (true or false) determines whether to enable logging or not. If not provided, defaults to false.
-N (int) specifies the number of threads to allocate. If not provided, defaults to 4.
To compile and run:

make
./httpserver [port] -l [true] -N [6]
