I have changed the keys in Lesti_Fpc 1.1.1. There was a problem with parameters in the Cache. Not a real problem, but the cache has produced too much keys. That means, more memory for the cache, but the real problem was, the cache had too much misses.
Events in magento are very cool. Mostly events make it possible to build very modular extensions for magento. In my first steps, I always searched for a full list of magento events. The problem with these lists were, they aren't complete and outdated. And you will never find dynamic events like this.
Mage::dispatchEvent($this->_eventPrefix.'_load_after', $this->_getEventData());A few weeks ago, I wanted to build a little analytics tool. The idea was to send anonym data , to improve the performace of a magento extension (only with the permission of the shopowner). A little bit like mozilla or PhpStorm asks you after the install. But before building a static and very special webservice only for my interests, I decided to search for a tool like this. A tool that can collect requests. And I found Piwiki. A free Web Analytics Software. All I needed was a mysql database and php. I installed it after 5 minutes and was ready to check every request on my blog. I can see every visitor and can see the main problems of my website. All these datas are hosted on my server. There was also a app for my smartphone. There are many plugins for magento, wordpress and so on. I'm that happy with this tool, that I wanted to write a little post about it.
In Lesti_Fpc 1.1.0 I created a new type of dynamic blocks. I call them lazy blocks. First I will explain what dynamic blocks are and what the difference to lazy blocks is.
Many full page caches are in front of Magento. Often Magento doesn't see the request. That makes external caches very fast. You only have to define a process in front of magento and send your own request. But external caches have to reload dynamic content with ajax and aren't that flexible. Lesti_Fpc has an other workflow.
Magento dependencies are quite easy to understand. One Extension needs an other extension. For example Mage_Page needs Mage_Core. But does it really make sense?
