What is the difference between sendRedirect and forward methods in Servlets?

Question

Aryan Kumar · Answer

In the world of servlets, both sendRedirect and forward methods are used for directing requests to other resources, but they serve different purposes.
sendRedirect:
Think of sendRedirect as telling someone to go to a different location by providing a complete address.It sends a response to the browser with a new URL, and the browser makes a new request to that URL.It involves two separate requests: the client makes a request to the first servlet, which responds with a redirect instruction, and then the client makes a new request to the redirected URL.
forward:
Think of forward as asking a friend to handle part of a task for you. It's a server-side redirection.It forwards the request to another resource (servlet or JSP) on the server without the client's involvement.It is more efficient because it happens entirely on the server without involving the client in the process.
Summary:
Use sendRedirect when you want to tell the client to make a new request to a different URL, and it involves two separate requests.Use forward when you want to handle part of the processing on the server and forward the request internally to another resource within the same request/response cycle.
Choose the method that best fits your use case depending on whether you need a client-side or server-side redirection.
