In ASP.NET Core, middleware components are used to handle requests and responses as they flow through the application's pipeline. These middleware components can be chained together to process requests and responses in a specific order. Transferring data between middleware components can be achieved using various techniques. Here are a few commonly used methods.
HttpContext.Items
The HttpContext class in ASP.NET Core provides a dictionary-like collection (Items) that allows you to store and retrieve data within the scope of a single HTTP request. This data can be accessed by any middleware component in the request pipeline.
