Installation
2.1
Instructions
• Backup your existing database
• Download and unzip extension in your Magento root folder
• Clear cache via “System > Cache Management > Flush Magento Cache” • Enable Full Page Caching in “System > Cache Management”
• Finally, modify your index.php file located in Magento root folder so it looks like this:
Important: if you have defined a default store view with a code different than “default”, you have to add another line that defines the default store view like below:
2.2
Multiple hosts
If you have defined several hosts on a same Magento installation, you have to configure what is the default store for each host in top of file index.php. Here is an example for a french store view with a specific host:
2.3
APC
If you are using APC as an opcode cache, you have to be aware of the configuration. Check if the directive apc.stat is set to Off (or zero). If it is, you have to define the full page cache directory as excluded by adding the directive:

Customization (for developers)
3.1
Accessing the configuration in Magento admin panel
3.2
Cacheable Actions
The default cached pages should be enough for improving performances of your Magento store. But you can add your own pages easily. You just have to follow the syntax <module>/<controller>/<action>. Here is an example:
If you don’t want an existing page to be cached, you can disable it by clicking the Edit link, see result below:
3.3
Dynamic Blocks
Default Magento dynamic blocks are already handled by FPC extension such as welcome message, flash messages, polls, cart items, etc.
However, sometimes you’ll have to add your custom logic because you have a dynamic block to show in your product page for example. This can be achieved easily with FPC thanks to an event that is dispatched when a page cache is generated.
Example of a custom dynamic block
1. Listen to the dispatched event
<!-- app/code/local/Your/Module/etc/config.xml --> <?xml version="1.0" encoding="UTF-8"?>
<config> <modules> <Your_Module> <version>1.0.0</version> </Your_Module> </modules> <global> <events> <bubble_fpc_layout_params>
7 <observers> <your_module> <class>your_module/observer</class> <method>onFullPageCacheGeneration</method> </your_module> </observers> </bubble_fpc_layout_params> </events> </global> </config>
2. Add your criteria in observer method
<?php
// app/code/local/Your/Module/Model/Observer.php class Your_Module_Model_Observer
{
public function onFullPageCacheGeneration(Varien_Event_Observer $observer) {
$layout = $observer->getEvent()->getLayout(); if ($layout) {
// Example of a country parameter added to all pages $layout->setCustomerCountry('France');
} } }

Cache generation methods
4.1
From Magento admin (recommended)
Go to “System > Configuration > Full Page Cache” and you will see the Store View tab by default:
Then, generate cache for a specific store view:
All URLs of the store will be called and the cache will be generated:
4.2
wget command
Generate cache via wget command is the most powerful method but it is also the longest because it generates the cache for all the pages. Here is an example of how to generate cache for all the pages of the default store view:
wget http://www.mystore.com -r --delete-after -nd -R png,jpeg,jpg,gif,zip,txt,pdf -X
"/customer,/checkout,/catalog,/wishlist,/tag,/sales" --cookies=off --header "Cookie: store=default" You are free to customize this command, for example by accepting only .html files:
wget http://www.mystore.com -r --delete-after -nd –A html --cookies=off --header "Cookie: store=default"
4.3
PHP script
The module comes with a PHP script that allows you to call all the URLs of a specific store.

php shell/fpc.php --generate --store default
Another example for french store view:
php shell/fpc.php --generate --store french
