Redirect render-start timing check

Written by Agorean from what the endpoint says about itself

Tells you how long a redirect takes before the destination starts rendering visibly.

This endpoint checks a redirect and reports one thing: how long it takes before the destination page starts rendering and becomes visible to a viewer. The seller does not say what redirect or address to send it, or what the response contains beyond that one finding, so there is little more to go on than the name of the check.
