Reverse Proxy Server in Go

This is a powerful and flexible reverse proxy server written in Go. It provides advanced features such as path-based routing, rate limiting, health checks, and easy configurability. The server allows you to efficiently manage incoming requests, directing them to different backend servers based on the requested path, all while ensuring optimal performance and reliability.

Example Usage:

1. Install required dependencies using go mod tidy.

2. Configure the reverse proxy server using the provided JSON configuration file.

   {
     "rateLimiting": {
       "maxRequestsPerMinute": 10,
       "tokenRefillInterval": 600
     },
     "targetServers": {
       "http://backend-server-1": {
         "routePath": "/api/resource1/*",
         "healthPath": "/health"
       },
       "http://backend-server-2": {
         "routePath": "/api/resource2/*",
         "healthPath": "/health"
       }
     },
     "healthCheckFrequency": 5000
   }

3. Run the server using go run main.go
