Well, this request is similar to the one ('wish for a new 
feature') few lines on top. To summarize, this would 
require some important changes in the way the engine cralws 
websites ; and I suspect the site to have implemented this 
to prevent offline browsers from crawling it. I have taken 
note of the problem, and see is something can be done ; but 
understand that I won't try to bypass measures taken by 
webmasters to limit mirrors/remote copies: it's up to them.
