- A HttpModule is core to the ASP.NET MVC framework, while a Middleware is native to the ASP.NET Core
- Both Middleware and HttpModule are pieces of code blocks which lets two or more components interact together during a request execution.
- HttpModules are registered in the web.config file of the ASP.NET framework while a Middleware is registered via code inside an ASP.NET Core application.
- The order of execution of HttpModules can’t be changed, while since the middlewares are wired programmatically within the code, their order or execution can be altered or skipped when needed.
