Steam Query Cacher

Proxy that lazy caches steam source server queries to prevent dos using A2S_INFO attacks. On windows you can set up a proxy for specific ports using the netsh portproxy interface, on linux you can use iptables.

⚠ Disclaimer ⚠

• Only caches A2S_INFO, A2S_PLAYER and A2S_RULES queries (others will get proxied without caching) with the simple response format!
• Tested on Squad dedicated servers under Windows.
• Not a ready-to-use project
• No Goldsource support!
• No support given, feel free to contribute tho
• Code is by no way considered "clean" as it's a hacked together project to suit specific needs

TODO

• Temporary ip blacklisting for invalid queries
• Ip based ratelimiting
• Make logs more concise as they are very messy and dont follow a clean guideline atm
• Code refactoring in general
