RCP - Rust CORS Proxy

RCP (Rust CORS Proxy) is a lightweight HTTP proxy server implemented in Rust that enables Cross-Origin Resource Sharing (CORS) for web applications. It allows you to make cross-origin requests to APIs or resources that would otherwise be blocked due to browser security policies.

Features

• Enables CORS for web applications by acting as a proxy server.
• Supports HTTP GET, POST, PUT, DELETE, and OPTIONS methods.
• Automatically adds appropriate CORS headers to the proxied responses.
• Provides a simple and straightforward implementation.

Installation

1. Install Rust on your machine.
2. Clone this repository.

git clone https://github.com/f-str/rcp.git

3. Build the project.

cd rcp
cargo build --release

Usage

1. Start the RCP server.

cargo run --release

2. RCP will start listening on 0.0.0.0:8080 by default.

3. Make requests to the RCP server by replacing the original URL with the RCP URL.

http://localhost:8080/original-url

For example, to proxy https://api.example.com/data, you would make a request to http://localhost:8080/https://api.example.com/data.

4. RCP will forward the request to the original URL and return the response with the appropriate CORS headers.

Configuration

RCP can be configured using environment variables:

• LOGGING_ENABLED: Set to "true" to enable logging (default: false).
• PORT: Set the port that RCP listens on (default: 8080).
• ADDRESS: Set the address that RCP listens on (default: 0.0.0.0).
• ALLOWED_DOMAINS: List of domains that can be proxied, comma separated (default: empty string, a.k.a no domain filtering)
