# Implementing RFC-compliant HTTP caching for HttpClient in .NET

**[Meziantou](https://daily.dev/sources/meziantou)** · 5 min read · 5 upvotes · 1 comments

## Summary

HttpClient in .NET lacks built-in HTTP caching, requiring every request to hit the server. The Meziantou.Framework.Http.Caching NuGet package adds RFC 7234 and RFC 8246 compliant caching via a DelegatingHandler. The post covers installation, basic usage, ASP.NET Core dependency injection integration, client cache directives (no-cache, max-stale, only-if-cached), configurable options like response size limits and custom cache predicates, and thread safety including cache stampede prevention.

> The C# HttpClient might not have it, but ASP NET Core does. In ASP it's called Response caching and is RFC 9111 compliant. RFC 9111 obsoletes RFC 7234
