@Umang01-hash , Can we also check and add tests for url with path and query params as well as request Bodies, headers etc.....get handled successfully through the redirect. I feel that is not the case right now.

Let's not have a redirect method. We can just expose response of redirect Type ..... Also, we must ensure the traces are in hierarchy.

I agree. Till now, all responses in Gofr are a type which is returned. ctx.Redirect is coming from other framework's behaviour where things like ctx.JSON etc are method. Also, we do not ask people to set manual status codes - but, we automatically decide. We should do the same and use a proper status code. The usecase in APIs for redirects are never going to be 301 - I think.
