AuthenticatorBase (Payara Project 4.1.2.174 API)

java.lang.Object
- org.apache.catalina.valves.ValveBase
- - org.apache.catalina.authenticator.AuthenticatorBase

All Implemented Interfaces:

Authenticator, Contained, Lifecycle, Valve, GlassFishValve

Direct Known Subclasses:

BasicAuthenticator, DigestAuthenticator, FormAuthenticator, NonLoginAuthenticator, SSLAuthenticator
```
public abstract class AuthenticatorBase
extends ValveBase
implements Authenticator
```
Basic implementation of the Valve interface that enforces the <security-constraint> elements in the web application deployment descriptor. This functionality is implemented as a Valve so that it can be ommitted in environments that do not require these features. Individual implementations of each supported authentication method can subclass this base class as required.
USAGE CONSTRAINT: When this class is utilized, the Context to which it is attached (or a parent Container in a hierarchy) must have an associated Realm that can be used for authenticating users and enumerating the roles to which they have been assigned.
USAGE CONSTRAINT: This Valve is only useful when processing HTTP requests. Requests of any other type will simply be passed through.

```
protected boolean alwaysUseSession
```
    Should a session always be used once a user is authenticated? This may offer some performance benefits since the session can then be used to cache the authenticated Principal, hence removing the need to authenticate the user via the Realm on every request. This may be of help for combinations such as BASIC authentication used with the JNDIRealm or DataSourceRealms. However there will also be the performance cost of creating and GC'ing the session. By default, a session will not be created.
