How to redirect without a round trip

To redirect without a round trip in ASP.NET, you can use the Server.Transfer method instead of Response.Redirect. The Server.Transfer method allows you to transfer the control from one page to another without the need for a round trip back to the client.

Server.Transfer method

Here's an example of how you can use Server.Transfer to perform a redirect without a round trip:

In this example, when the Page_Load event is triggered, the control is immediately transferred to the "DestinationPage.aspx" without sending a response back to the client. The client is unaware of this transfer and the URL in the browser remains the same.

Conclusion

It's important to note that when using Server.Transfer, the target page must be within the same application and the URL in the browser will not change. If you need to redirect to a different application or change the URL visible to the user, you can still use Response.Redirect.
