Recycling a conn tries to do essentially the same as what happens when a browser would navigate to a new route. Only things like cookies, some headers, hostname, … will be retained. assigns are not retained between multiple requests being made, but need to be computed and set freshly for each request, so the same applies with recycles.
Here you have a conn, which was already used to do a request, then you assign some data and then you request a new page, trigger a recycle and therefore get rid of tje assign again.
If you do multiple request you likely want to authenticate, so that a session is started and not just for a single request by setting just assigns.
