A simple caching HTTP-only webproxy supporting HTTP/1.1. This project was written for ECEN 5273 - Network Systems at the University of Colorado - Boulder. This is a toy project and shouldn't be used for anything serious, but was the first C project I ever wrote that got big enough to where I needed unit tests to keep from getting overwhelmed.
$ mkdir build
$ cd build
$ cmake ../
$ make && make test
$ ./src/toyproxy 10000 # start on port 10000Use --debug flag to enable debug output.
Toyproxy is a multithreaded HTTP proxy that implements a subset of HTTP/1.1. It includes a custom written url parser and hashmap caching implementation with unit tests. Request and response parsing is also unit tested. It implements multiple simultaneous requests, user-definable cache timeout, page and hostname caching, and URL and IP blacklisting.
Directories:
- src - The toyproxy source files
- vendor - Files for Unity, a small C unit testing framework
- tests - Unit tests for several of the fundamental data structures and parsing routines
Implementation Files:
- toyproxy.c - "Configuration" defines (
CACHE_ROOT,BLACKLIST_FILE,KEEPALIVE_TIMEOUT, ...),mainfunction, proxy main loop, socket connection handling, etc - url.h - Url struct and related functions header
- url.c - Url struct and related functions implementation
- hashmap.h - Hashmap struct and related functions header
- hashmap.c - Hashmap struct and related functions implementation
- request.h - Request struct and related functions header
- request.c - Request struct and related functions implementation
- response.h - Response struct and related functions header
- response.c - Response struct and related functions implementation
- printl.h - Printk-like logging function header
- printl.c - Printk-like logging function implementation
- queue.h - Thread-safe FIFO queue header (not currently used)
- queue.c - Thread-safe FIFO queue implementation (not currently used)
