Non-Blocking Cache

Implement a non-blocking cache that stores previously fetched responses from URLs. The cache should:

• Return cached data if the requested URL has been fetched before.
• Fetch and store new data asynchronously if the URL is not in the cache.
• Ensure multiple concurrent requests for the same URL do not trigger multiple fetches.
