Nov 2, 2012 · 9. HTTP/2 is stateful. HTTP 1 is stateless. Later additions intended for HTTP 1, like cookies, added state. Those additions are not apart of the "core" HTTP 1 specification. This is why HTTP 1 is said to be a stateless protocol although in practice it is not. HTTP/2 on the other hand was designed with stateful components baked in.
120. Stateless means there is no memory of the past. Every transaction is performed as if it were being done for the very first time. Stateful means that there is memory of the past. Previous transactions are remembered and may affect the current transaction. Stateless: // The state is derived by what is passed into the function.
A stateless protocol does not require the server to retain information or status about each user for the duration of multiple requests. For example, when a web server is required to customize the content of a web page for a user, the web application may have to track the user's progress from page to page.
Dec 7, 2015 · The stateless constraint. The REST architectural style is defined on the top of a set constraints that include statelessness of the server. According Fielding, the REST stateless constraint is defined as the following: 5.1.3 Stateless
Main difference between @RequestScoped vs @Stateless in this scenario will be that the container can pool the EJBs and avoid some expensive construct/destroy operations that might be needed for beans that would otherwise be constructed on every request. edited Aug 2, 2016 at 4:24.

Dec 5, 2018 · 1)if everything is a session bean, then performance will suffer due to container overhead. 2)Making utility classes session beans isn’t terribly useful (A utility API should probably just use CDI and not EJB) 3) DAO/repository classes. Although these objects rely on thread safety and transactions, they don’t need to be session beans ...
Apr 12, 2015 · Stateless object is an instance of a class without instance fields (instance variables). The class may have fields, but they are compile-time constants (static final). A very much related term is immutable. Immutable objects may have state, but it does not change when a method is invoked (method invocations do not assign new values to fields).
TLS/SSL is stateful. The web server and the client (browser) cache the session including the cryptographic keys to improve performance and do not perform key exchange for every request. HTTP 1 is not stateful. HTTP/2 however defines many stateful components, but the "application layer" still remains stateless. TL;DR: The transport pipe (TLS) is ...
Apr 29, 2011 · Stateless servers are also easily scalable, while for stateful servers scalablity is problematic. Stateless request can be sent to any node, at any time, while with Stateful this is not a case. HTTP as Stateless protocol increases availability for stateless web applications, which otherwise would be difficult or impossible to implement.
Jan 3, 2019 · Stateless in HTTP terms means that each request has no knowledge of any prior request, i.e, there is no built-in mechanism in HTTP to track who is making requests and the effects of those requests. In terms of RESTful services, it means that each request doesn't rely on state, e.g., saved client info, to fulfill a request -- all information ...
