What is the difference between the request scope and session scope in JSF?

In JSF, the request scope and session scope are two common ways to manage the lifespan of managed beans:

Request Scope:

• Request scope is the shortest-lived scope in JSF.
• It is created for each HTTP Request and destroyed after the response is sent back to the client.
• Managed beans in request scope are not available across multiple requests.

Session Scope:

• Session scope lasts for the entire session of the user interacting with the application.
• It is created when the user session starts and destroyed when the user session ends.
• Managed beans in session scope can retain their state across multiple requests from the same user.

It is important to choose the appropriate scope based on the requirements of your application to manage the bean's lifespan efficiently.
