HTTP Proxy

HTTP Proxy is a lightweight HTTP reverse proxy written in Go. It listens on a given address and port, and forwards all HTTP requests to a specified target server. It's ideal for simple debugging, local forwarding, and lightweight HTTP routing tasks.

📦 Install

go install github.com/sebps/http-proxy

🚀 Features

• Forwards all incoming HTTP requests to a target host and port
• Logs request method, path, and body
• Optional automatic CORS headers via --withCors
• Clean CLI with --help, --targetHost, --targetPort, --targetProtocol, --sourceAddr, and --sourcePort
• Simple and minimal — no external dependencies beyond Go stdlib

🛠️ Usage

http-proxy [options]

Options

Flag	Description	Default
--targetHost	Target host to forward requests to (required)
--targetPort	Target port to forward requests to	80 or 443 based on protocol
--targetProtocol	Protocol to use to reach the target (http or https)	http
--sourceAddr	Source address to bind the proxy server	localhost

🧪 Examples

Start a proxy that listens on port 8888 and forwards to https://example.com with CORS support:

./http-proxy --targetHost example.com --targetProtocol https --sourcePort 8888 --withCors

Bind to all interfaces instead of just localhost:

./http-proxy --targetHost example.com --targetPort 443 --targetProtocol https --sourceAddr 0.0.0.0

🔎 Example Log Output

🚀 HTTP Proxy starting on http://localhost:8888
