For Duke ECE 568 Robust Sever HW2

erss-hwk2-aw343-wl177

This project is for ECE-568 Homework2 For this assignment you will be writing an http proxy – a server whose job it is to forward requests to the origin server on behalf of the client. Your proxy will cache responses, and, when appropriate, respond with the cached copy of a resource rather than re-fetching it.

Getting Started

2. cd erss-hw2-aw343-wl177
3. sudo docker-compose up
4. use your browser(Expected Firefox) to check
5. exam the /var/log/erss/proxy.log file
