Provides a particular shipping rate webserver using Inchoo_Unicache extension. It's a requirement that you have installed and not used Inchoo_Unicache extension. For a simple usage, update your request client URI to http://www.example.com/unicached/shipping_rate/. It's optional but recomended to disable the cache cleaning, removing "crontab" tag from /app/code/community/Inchoo/Unicache/etc/config.xml.
