Some servers, instead of giving a clean error page 
when you request an URL which does not exists, 
redirect you to a generic page using a HTTP move error 
code. This is quite dirty, but sometimes used. Anyway, 
the messages you see shows that these pages are 
missing..

Yes. This can result in a HUGE amount of data, so 
beware!

Questions will be asked when a new URL is reached, to 
decide if you want -or not- to download it.
