- A simple, multi-threaded
HTTP/1.0proxy server. - It's the 7th and last lab of 15-213: Introduction to Computer Systems.
- It uses a cache of size
1MBto store reciently used requests.
proxy.c contains:
-
The
mainfunction which:- Opens a listening desctiotor for requesting clients requests.
- Initializes the cache.
- Accepts a connection with each client.
- Creates a peer thread for each client.
-
The
threadfunction which:- Detaches itself from the
main thread. - Reads client request and headers.
- If it's a valid request, it searches in the cache for the request, if present it sends it directly to the client
- If not present, then it parses the request.
- and opens a connection with the server the client requested.
- and serves the client, then forwards it content to it.
- lastly, it caches this request if it comes in the future.
- Detaches itself from the

git clone https://github.com/Alighorab/Proxy-Server/
cd Proxy-Server/
make
./proxy <port> (e.g., 4000)
