Package io.milton.http.http11.auth

Class PreAuthenticationFilter

java.lang.Object

io.milton.http.http11.auth.PreAuthenticationFilter

All Implemented Interfaces:

Filter

public class PreAuthenticationFilter
extends Object
implements Filter

A filter to perform authentication before resource location.

This allows the authenticated context to be available for resource location.

Note that this filter contains a list of AuthenticationHandler. However, these handlers MUST be designed to ignore the resource variable as it will always be null when used with this filter. This approach allows these handlers to be used with the post-resource-location approach.
