This project is a fast and efficient URL shortener service built with Go. Users can submit long URLs, and the system generates a short code. Accessing the short code will redirect to the original URL. Perfect for learning, demos, and small applications.

• Randomly generates 6-character short codes to avoid collisions
• In-memory storage for fast mapping between short codes and long URLs
• Simple and easy-to-use API endpoints
• Well-commented code, easy to extend

1. Start the service

   go run main.go

2. Shorten your long URL

   curl -X POST -H "Content-Type: application/json" \
       -d '{"url":"https://www.example.com"}' \
       http://localhost:8080/shorten

     Example response:
     ```json
     {
         "short_url": "/abc123",
         "link": "http://localhost:8080/abc123"
     }
     ```
   

3. Access the short code for redirection

   Open in browser or use curl:

   http://localhost:8080/abc123
   

   You will be redirected to the original long URL.

• Uses Go standard library net/http for web service
• Thread-safe in-memory storage (sync.RWMutex)
• Random short code generation algorithm, supports high concurrency
• Clean code structure with detailed comments

• This version uses in-memory storage only; data will be lost after service restart
• Suitable for learning and small projects; for production, consider using a database
