The purpose of this project was to create a robust high performance proxy with the following features:
- HTTP caching
- CONNECT tunneling(HTTPS)
- Handling partial messages
- Rate limiting via the bucket method
| File | Functionality |
|---|---|
| proxy.c | Proxy Implementation-- all files moved into here for performance and grading |
| Bucket.c/h | Leaky/Token Bucket algorithm to limit and regulate network |
| Buffer.c/h. | Stores partial messages in a buffer so complete packets can be handled |
| CacheObject.c/h | Object that is stored within the cache |
| cache_tests.c | Tests CacheObject |
| HandleMessage.c/h | Handles messages from clients and servers and stores partial messages in a buffer array |
| HttpCache.c/h | Store and query and delete cache objects |
| RequestParser.c/h | Parse a HTTP requests by taking in a buffer and storing it in struct which has values for every possible optional argument |
| ServerHandler.c/h | Communicates with servers and keeps track of which servers we're talking to |
| baseline_unit_tests.c/h | Unit tests for baseline functionality without Rate limiting |
| utarray.h | dynamic array implementation |
| uthash.h | hash table implementation |
We can see that we get relatively stable performance with fixed number of clients but we have decreasing performance with more clients. This shows how rate limiting allows us to manage performance against greedy clients but is still susceptible to a denial of service style attack
