This one is nearly similar to the one above. It might be more efficient.
sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder;say cache flushed

Might work only on chrome os?
Delete browser cache in options might also have an effect.
"Go to tools -> options -> Under the hood -> Clear Browsing data and check 'empty the cache' and click on clear browsing data.
