Operation:

The server listens on port 8888 for client requests. Once the client establishes a connection and send a GET request, the server parses the request to extract the hostname and path(Host: example.com, Path: /index.html). The server proceed to check the path(filename) across the cache directory, if it checks out. it send the cached file to the client. If there's no corresonding file in the cache, it forwards the request to the necessary web server to get the needed file.

The response from the web server is cached in the cache folder before being sent to the client.
