I've been doing some underground work with a few websites that need to use redirects however they are are getting "bot checked" and then deleted. I have got around this by burning redirects. However for the "real" traffic I'm targeting I want the redirect to unmask itself after a few seconds so they see the real site. I'm not trying to block there robot I'm looking for an exact way to unmask. This is a technique I will be adding into my next guide but want to make sure it works so if you can contribute some info let me know.
