Feature Request: Built-in Bandwidth Limiting Support for ProxyChain #586
Description
Hello, thank you for the amazing work on proxy-chain!
I'm requesting a feature to support built-in bandwidth throttling for incoming/outgoing traffic. Currently, proxy-chain does not provide any option to limit bandwidth per connection or globally. To achieve this, users have to manually use stream-throttle or similar libraries and hook into raw TCP connections using server.server.on('connection').
However, this approach is low-level, error-prone, and may break internal handling (e.g., TLS tunnels, HTTP parsing, etc.). Having official support for throttling would make it easier to:
- Limit bandwidth per connection (e.g., 10 Mbps per client)
- Set global bandwidth limits for the proxy server
- Prevent abuse or overload of upstream proxies
- Simulate network conditions for testing
Suggested API Design:
const server = new ProxyChain.Server({
port: 8000,
bandwidthLimit: {
rate: 10 * 1024 * 1024, // bytes per second
perConnection: true // or false for global throttle
}
});
