This chapter covers

Injecting logic into request pipelines
Understanding the different filter types and when each is executed
Creating and applying filters
Managing the filter lifecycle and execution order

Filters inject extra logic into request processing. Filters are like middleware that is applied to a single endpoint, which can be an action or a page handler method, and they provide an elegant way to manage a specific set of requests. In this chapter, I explain how filters work, describe the different types of filters that ASP.NET Core supports, and demonstrate the use of custom filters and the filters provided by ASP.NET Core. Table 30.1 provides a guide to the chapter.
