The url, above, contains: meta name="robots" content="noindex,nofollow" 
This is the secondary form of robots.txt. 
Override robots.txt, use the near flag (get non-html related)

A mirror is not a copy, it is a static copy, a snap shot, a collection of
files. Forms or anything that requires a web sever will not work. 
If you are the owner of the site, go through the private, not the public side
and save the files/DB.
