Update Docker configuration and Nginx settings to use a new image and improve caching logic

README.md

 ## Usage
 
-```bash
-# Normal request - NOT cached (default)
-curl http://localhost:3000/?url=https://api.example.com/data
+Both URL formats are supported:
 
-# Cached request - add the header
-curl -H "X-Cache: 1" http://localhost:3000/?url=https://api.example.com/data
+```bash
+# Path-based URL format (recommended)
+curl http://localhost:3001/https://api.example.com/data
+
+# Query parameter format (legacy)
+curl "http://localhost:3001/?url=https://api.example.com/data"
+
+# Enable caching with X-Cache header
+curl -H "X-Cache: 1" http://localhost:3001/https://api.example.com/data
