A specialized class using memcached to track items stored. It supports three operations: new, <<, and include? . Together these can be used to add items to the memcache, then determine whether the item has been added.
To use it with Spider use the check_already_seen_with method:
Spider.start_at('http://example.com/') do |s| s.check_already_seen_with IncludedInMemcached.new('localhost:11211') end
Construct a new IncludedInMemcached instance. All arguments here are passed to MemCache (part of the memcache-client gem).
