Explaining Forward and Redirect in Struts for Interviews

Forward and redirect are two essential concepts in Struts, often used for navigation and control flow handling in web applications. Let's define and differentiate between them:

Forward in Struts:

The forward method in Struts is used to forward the processing of a request from one Action class to another without the client being informed. This means the request is internally forwarded within the server, maintaining the same URL in the browser.

Redirect in Struts:

On the other hand, redirect is used to redirect the client to a new URL or location. This results in a new request being made by the client to the redirected URL, causing the URL in the browser to change.

When to Use Forward vs. Redirect:

Use forward when you want to pass control from one resource to another within the server, typically for internal navigation and processing. On the other hand, redirect should be used when you want the client to make a new request to a different URL, such as after form submissions or to prevent re-submission of data.

Understanding when and how to use forward and redirect in Struts can significantly enhance the navigation and user experience in your web applications.
