sendRedirect

sendRedirect is a method in the HttpServletResponse class in Java that is used to redirect the user's request to a different URL.

When a user sends a request to a server, the server can use sendRedirect to redirect the user to a different URL. This is useful in situations where the requested resource has been moved or is no longer available at the original URL, or when the user needs to be redirected to another page after completing an action.

The syntax for sendRedirect is:

response.sendRedirect("newUrl");

Where "newUrl" is the URL that the user will be redirected to. After the redirect, the server will send a new response to the user's browser with the new URL.

It is important to note that sendRedirect creates a new request and response, so any data that was stored in the original request or response will be lost. Additionally, the new URL must be within the same domain as the original URL to avoid security issues.
