Magento Cache Management
This is an old revision of the document!
This screen will allow you to manage cache settings for different internal Magento aspects.
In this fieldset you are presented with checkboxes, which, if checked, will enable cache for each aspect as described below.
During developing, i.e. changing files or database directly, disable all cache to avoid undefined behaviour.
After extension upgrade, installation or uninstallation, refresh all cache.
This select box is a convenience feature to apply an action to all checkboxes.
- No Change - No action will be taken that will affect all aspects.
- Refresh - All cache will be cleaned, but all enabled aspects will remain enabled.
- Disable - Disable all cache.
- Enable - Enable all cache.
All configuration is kept in XML files and database table core_config_data. Data from these files and table is collected, merged and saved in the cache.
app/etc/config.xml- default core configuration
app/etc/local.xml- local database connection configuration, saved during Magento install wizard.
app/etc/distro.xml- used when local.xml is not available (during first steps of installation wizard)
app/etc/modules/*.xml- modules declarations
app/code/<codePool>/<namespace>/<module>/etc/config.xml- module configuration
Layouts are XML instructions of blocks combinations.
Caches HTML output from blocks.
Note: dynamic data generated in block classes will be cached too.
