What is difference between Server.transfer and Response.Redirect in ASP.Net?
Server.Transfer and Response.Redirect are both methods used in ASP.NET for transferring a user's request from one page to another. However, they differ in their implementation and behavior:Use Server.Transfer when you want to transfer control to another page on the server side without changing the URL in the browser and without a round-trip to the client. This is useful for scenarios like transferring control to an error page or for internal navigation within your application.Use Response.Redirect when you want to redirect the user to a different page with a new URL. This will result in a round-trip to the client and changes the URL in the browser. This is useful for scenarios like handling form submissions, enforcing HTTPS, or redirecting users to a login page when they are not authenticated.
In ASP.Net, the primary difference between Server.Transfer and Response.Redirect lies in how they handle page transfers.
Server.Transfer: This method transfers control directly to the target page on the server-side without the client’s knowledge. It preserves the original URL in the browser, making it a server-side operation. However, it can only transfer control within the same application.
Response.Redirect: In contrast, this method sends a redirect message to the client, instructing the browser to navigate to the new page. It results in an additional round trip to the server as the client initiates a new request. This method is suitable for redirecting to external URLs or different applications.
Choose Server.Transfer for internal page transfers within the same application without changing the URL visibly, while Response.Redirect is ideal for redirecting to external pages or applications.
