Go Reverse Proxy Server

This repository contains a Go program that sets up a reverse proxy server. The server forwards incoming HTTP requests to a specified target URL and uses an external proxy for the outgoing requests.

Features

• Configurable via environment variables
• Removes certain headers from incoming requests before forwarding
• Uses an external proxy server for outgoing requests
• Logs request details for debugging purposes

Environment Variables

The program uses the following environment variables for configuration:

• PORT: The port on which the server will listen (default: 8080).
• PROXY_URL: The URL to which the incoming requests will be proxied (default: https://api.openai.com).
• EXT_PROXY_URL: The URL of the external proxy server (default: http://10.0.0.8:8080).

Getting Started

Prerequisites

• Go (version 1.16 or later)
• Docker

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/reverse-proxy-server.git
   cd reverse-proxy-server

2. Build the Go program:

   go build -o reverse-proxy main.go

Usage

Running Directly

1. Set the necessary environment variables:

   export PORT=8080
   export PROXY_URL=https://api.openai.com
   export EXT_PROXY_URL=http://10.0.0.8:8080

2. Run the server:

   ./reverse-proxy

Running with Docker

1. Build the Docker image:

   docker build -t reverse-proxy-server .

2. Run the Docker container:

   docker run -d -p 8080:8080 \
       -e PORT=8080 \
       -e PROXY_URL=https://api.openai.com \
       -e EXT_PROXY_URL=http://10.0.0.8:8080 \
       reverse-proxy-server

The server will start listening on the specified port and proxy requests to the configured URL.
