Serve old content if backed is slow.

[Damien Wetzel]

Hello,
Something that could be usefull in a subsequent release would be
to return in case of unavailibily of the backend :
1) a stale copy for any non html object or a null sized object if that object
   is not in cache. 
2) a stale copy of an html url or a user defined static html page 
   if that html page is not in cache.
Damien,
