@methode In this use case we don't want the first URL (that redirects) to be indexed, so it has a noindex directive in the header. If the final destination (eventually, after a few redirects potentially) is a valid page with a 200, does that 200 impact the previously encountered URLs, possibly resulting in the page with the noindex to be indexed anyway? (Thinking about the chain in the opposite direction: does a subsequently encountered URL impact previously encountered URL in a redirect chain?)

@methode And for more clarification: this particular use case the noindex, nofollow directives are in the HTTP header, so crawling the HTML would not be required to see the directives

@methode Will directives (noindex, nofollow) from a URL that redirects (301, 302) be respected or ignored?
