rust-cors-proxy

A lightweight HTTP/HTTPS proxy server written in Rust that safely forwards requests, blocks private network addresses, and logs each request with method, URL, resolved IPs, and status.

Features

• Forwards HTTP/HTTPS requests to specified URLs.
• Prevents SSRF and DNS rebinding attacks.
• Blocks private, loopback, link-local, multicast, unspecified, and unique-local IPs.
• Handles CORS preflight requests and adds CORS headers to responses.
• Logs request method, target URL, resolved IPs, and upstream status.
• Built using warp, reqwest, tokio, and serde_json.

Usage

Run the proxy locally:

cargo run --release

By default the server listens on:

http://127.0.0.1:8080

To make a request through the proxy:

http://127.0.0.1:8080/https://example.com
