## What it is
ProxyKit is a .NET library for building code-first HTTP reverse proxies as ASP.NET Core middleware, supporting request/response interception, X-Forwarded headers, WebSockets, and load balancing. It is now obsolescent, with Microsoft's YARP recommended as the replacement.

## Use cases
- build a reverse proxy in asp.net core
- route requests based on jwt claims
- rewrite proxy request and response headers
- proxy websockets through asp.net core
- embed a reverse proxy in an existing dotnet app
- weighted round robin load balancing in c#

## When to choose
- you need a lightweight, code-first reverse proxy embedded in an existing ASP.NET Core app
- you need fine-grained programmatic control over proxied requests and responses
- you are maintaining an existing ProxyKit-based codebase

## When to avoid
- starting a new project - use Microsoft's YARP instead
- you need config-driven or feature-rich proxying with active maintenance
- you need guaranteed long-term support, since the project is obsolescent

## Facets
- artifact type: library
- maturity: maintenance
- function: proxy, middleware, http-server, routing, websocket
- domain: web-development, backend, networking, microservices
- platform: dotnet, cross-platform, serverless
- tags: reverse-proxy, aspnetcore, code-first, http-proxy, obsolete, yarp-alternative, docker, web-server
