title: Is a redirect less efficient than returning other types of result?
body: <p>Is a redirect less efficient than returning other types of result? I ask because if my current request is asynchronous I want to return a partial with only relevant data. Otherwise I need to render the entire page. So I'm thinking of returning a redirect to an action method which will return a View. My understanding is that a redirect will respond to the browser instructing it to request the new url. This effectively means 2 requests. Is the overhead substantial? Is this bad practice? What will this mean in terms of SEO?</p>
