Since the NoIndex directive will no longer have effect on Robots.txt file, how you will address to use NoIndex to directories or folders? An important thing to mention is that we also want to disallow these directories.
In a Google Webmaster Blog Post, I read that if I want to place a NoIndex on Meta or Http header having a Disallow on the Robots.txt, the NoIndex will no longer take effect.

The real question is... How can I place a NoIndex and Disallow at the same time?
