Simple implementation of reverse proxy caching server in Rust for learning purpose.
Caches all incoming GET request by HTTP method and path. Uses LRU or LFU caching algorithm, default size of cache is 4096 items. Spawns 4 threads by default to process incoming requests.
To configure backend server address, you need to create config.txt with its address in format 127.0.0.1:3000
To configure number of threads, use CACHING_SERVER_N_THREADS environment variable
To configure maximum cache size, use CACHING_SERVER_MAX_CACHE_SIZE environment variable
To configure caching alghoritm, use -a or --algo command-line option. Possible values: LFU, LRU (default LRU)
