By default, Magento is not cacheing CMS Blocks. But in almost all stores, there is a huge chance to use a bunch of CMS Blocks. So cacheing static blocks become important in that case for better page load performance.
This module will fill this gap. This module enable us to cache static blocks uniquely. That is for each static blocks, this will use a unique cache key. Default cache time is set to the default cache life time of Magento (ie 2 hrs).
