# URL Pattern Matching in .NET

**[Meziantou](https://daily.dev/sources/meziantou)** · 2 min read · 29 upvotes · 4 comments

## Summary

The Meziantou.Framework.Uri NuGet package brings the WHATWG URL Pattern API specification to .NET, enabling standardized URL pattern matching with named parameters, wildcards, optional segments, case-insensitive options, and pattern collections. The UrlPattern class supports both object-based and string-based pattern creation, making it useful for routing, security policies, and content filtering without resorting to custom regex.
