Here’s a technical write-up on using — focused on integration, signed URLs, caching strategies, and secure delivery. Title: Delivering Secure and High-Performance Content: Using AWS CloudFront with .NET 1. Overview AWS CloudFront is a global content delivery network (CDN) that accelerates delivery of static and dynamic web content. When paired with a .NET backend (ASP.NET Core, minimal APIs, or legacy .NET Framework), it improves latency, reduces server load, and enhances security.
