I was wondering what the purpose of wrapping a redirect_to in a
format.html block is. I get why you’d want to do this with a render,
but if you’re redirecting the browser to another URL, what’s the
point? As I understand it, when redirect_to is called, Rails sends a
302 back to the browser, so I’m having trouble understanding why
format plays any part in this. No biggie, just need some clarification
on what’s actually happening.
