A .NET library that implements HTTP 304 Not Modified responses by leveraging database change tracking to generate ETags from last-updated timestamps. It supports SQL Server and PostgreSQL, both directly and via Entity Framework Core, reducing server load for read-heavy workloads.

Use cases

• implement 304 Not Modified responses in ASP.NET Core
• generate ETags from database change tracking
• reduce server load for read-heavy APIs
• enable browser caching of dynamic content
• add HTTP caching backed by SQL Server or PostgreSQL
• integrate ETag handling with Entity Framework Core

When to choose

• your data updates infrequently relative to reads
• you want browser caching for dynamic content without manual ETag logic
• you use SQL Server or PostgreSQL with or without EF Core in a .NET app

When to avoid

• your data changes very frequently, making 304 responses rare
• you need per-entity or per-resource granular caching rather than a global last-updated timestamp
• you are not on the .NET stack
