# 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.

See: Description

Interface Summary
HttpServletRequest: Extends the `ServletRequest` interface to provide request information for HTTP servlets.
HttpServletResponse: Extends the `ServletResponse` interface to provide HTTP-specific functionality in sending a response.
HttpSession: 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.
HttpSessionActivationListener: 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.
HttpSessionAttributeListener: This listener interface can be implemented in order to get notifications of changes to the attribute lists of sessions within this web application.
HttpSessionBindingListener: Causes an object to be notified when it is bound to or unbound from a session.
HttpSessionContext: Deprecated As of Java(tm) Servlet API 2.1 for security reasons, with no replacement.
HttpSessionListener: Implementations of this interface are notified of changes to the list of active sessions in a web application.

Class Summary
Cookie: Creates 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.
HttpServlet: Provides an abstract class to be subclassed to create an HTTP servlet suitable for a Web site.
HttpServletRequestWrapper: Provides a convenient implementation of the HttpServletRequest interface that can be subclassed by developers wishing to adapt the request to a Servlet.
HttpServletResponseWrapper: Provides a convenient implementation of the HttpServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet.
HttpSessionBindingEvent: Events of this type are either sent to an object that implements `HttpSessionBindingListener` when it is bound or unbound from a session, or to a `HttpSessionAttributeListener` that has been configured in the deployment descriptor when any attribute is bound, unbound or replaced in a session.
HttpSessionEvent: This is the class representing event notifications for changes to sessions within a web application.
HttpUtils: Deprecated As of Java(tm) Servlet API 2.3.
