The extension already caters for multiple stores and multiple currencies, and even takes into account tax according to a logged in users location. It can also cache by user agent allowing separate caching of mobile stores under the same domain, and has the ability to output headers which are normally lost when using full page caching.
Another great feature is it's integration with Varnish. The extension will run all the logic for you in deciding how a page should be cached and can generate a cookie containing a unique hash relating to that page. All Varnish needs to do is pull the full page HTML and store it against the value in the cookie, massively simplifying your Varnish configuration and completely removing all of the usual headaches you come across when caching Magento pages. So even if Varnish is serving most of your pages, this is still a must have extension purely because of the logic it runs and the way it integrates with, and greatly simplifies your Varnish configuration.
On top of these existing features, version 1.2.0 also has these valuable additions:
- APC caching support
- Cache expiration for Memcached and APC to for a much better memory based caching strategy
- Dynamic updating of category page prices for complex, user specific pricing strategies
- Dynamic updating of category page product stock status
- Dynamic updating of category page review summary blocks
- Dynamic updating of product page review summary block
It's generally accepted that no Magento full page caching solution is complete and does not fully cater for the breadth of variation that can occur when thinking about things like having a complex, customer group based pricing structure, or having category and product pages correctly keep track of the stock status. Indeed if you run some simple tests with other full page caching solutions you will very quickly find them lacking, many even with the common task of correctly keeping track of product stock.
Well this isn't the case anymore, you can purchase Evolved Caching confident in the knowledge that it will not only deliver a massive performance increase, but will also be guaranteed to cater, in full, for your store configuration whatever it is.
