Package javax.servlet.http
package javax.servlet.http
The javax.servlet.http package contains a number of classes and interfaces
that describe and define the contracts between a servlet class
running under the HTTP protocol and the runtime environment provided
for an instance of such a class by a conforming servlet container.

ClassDescriptionCreates a cookie, a small amount of information sent by a servlet to a Web browser, saved by the browser, and later sent back to the server.Provides an abstract class to be subclassed to create an HTTP servlet suitable for a Web site.Extends the
ServletRequest
interface to provide request information for HTTP servlets.Provides a convenient implementation of the HttpServletRequest interface that can be subclassed by developers wishing to adapt the request to a Servlet.Extends theServletResponse
interface to provide HTTP-specific functionality in sending a response.Provides a convenient implementation of the HttpServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet.Provides a way to identify a user across more than one page request or visit to a Web site and to store information about that user.Objects that are bound to a session may listen to container events notifying them that sessions will be passivated and that session will be activated.This listener interface can be implemented in order to get notifications of changes to the attribute lists of sessions within this web application.Events of this type are either sent to an object that implementsHttpSessionBindingListener
when it is bound or unbound from a session, or to anHttpSessionAttributeListener
that has been configured in the deployment descriptor when any attribute is bound, unbound or replaced in a session.Causes an object to be notified when it is bound to or unbound from a session.Deprecated.As of Java(tm) Servlet API 2.1 for security reasons, with no replacement.This is the class representing event notifications for changes to sessions within a web application.Implementations of this interface are notified when anHttpSession
's ID changes.Implementations of this interface are notified of changes to the list of active sessions in a web application.Interface between the HTTP upgrade process and the new protocol.Deprecated.As of Java(tm) Servlet API 2.3.This class represents a part as uploaded to the server as part of amultipart/form-data
request body.The interface used by anHttpUpgradeHandler
to interact with an upgraded HTTP connection.
