    What is Auth filter?

    The certification filter is the component that typically performs the authentication of an HTTP request.

    Why Filters Are Needed At All

    The WebLogic Security Framework allows a person to provide a personalized authentication service. However, due to the core of the Java Servlet API 2.3 specification, the interaction between the authentication provider and the client or servers is architecturally restricted during our own authentication process. This limits tactical authentication to those that match the authentication mechanisms provided by the Servlet container ov: basic, formal and, in addition, certificate.

    How useful are authentication filters?

    ASP.NET MVC filters are used to create additional logic when MVC Framework requests are handled differently. The authentication filter runs before any other filter or action method. Authentication confirms whether you are a valid or invalid user. These filters implement each IAuthenticationFilter interface andbase class ActionFilterAttribute.
