Can we check ``is_redirect_required()`` here?
> Off-by-one error in max redirects with redirection enabled
> ----------------------------------------------------------

> Key: TS-4396
> URL: https://issues.apache.org/jira/browse/TS-4396
> Project: Traffic Server
> Issue Type: Bug
> Components: Core, Network
> Reporter: Felix Buenemann
> Assignee: Zhao Yongming
> Fix For: 7.0.0
>
>
> There is a problem in the current stable version 6.1.1 where the setting
> proxy.config.http.number_of_redirections = 1 is incorrectly checked when
> following origin redirects by setting proxy.config.http.redirection_enabled =
> 1.
> If the requested URL is not already cached, ATS returns the redirect response
> to the client instead of storing the target into the cache and returning it
> to the client.
> The problem can be fixed by using proxy.config.http.number_of_redirections =
> 2, but we are only following one redirect, so this is wrong.
