Cache¶

eZ Commerce uses different caches, including HTTP cache, which can greatly increase shop performance. Dynamic parts of the shop such as basket preview or prices are displayed using dynamic caching features such as ESI or JavaScript.

This ensures that only small parts of a page have to be generated in real time.

Usaging ESI-rendered blocks¶

Controller	Purpose	Cache settings
`SilversolutionsEshopBundle:CustomerProfileData:showHeaderLogin`	Displays information about the logged-in user in the top part of the page	Purged after login/logout and delegate process
`SilversolutionsEshopBundle:Basket:showBasketPreview`	Displays a short version of the basket in the top part of the page	Purged when basket changes. Tags: `siso_basket_<basketid>` `siso_user_<userid>`
`SilversolutionsEshopBundle:PageLayout:getFooter`	Footer information shared among all pages	caching strategy `service_menue`
`SilversolutionsEshopBundle:Bestsellers:getBestsellersEsi`	Bestseller Box for catalog pages	caching strategy `product_list`
`SilversolutionsEshopBundle:Bestsellers:getCategoryBestsellers` `SilversolutionsEshopBundle:EzFlow:showLastViewedProducts`	Shows last viewed products e.g. on Landing Page	caching strategy `product_list`
`SisoSearchBundle:Search:productList`	Shows the product list for the logged-in user	no caching
`SilversolutionsEshopBundle:ProductType:productList`	Product type list page	caching strategy `product_type_children`
`SilversolutionsEshopBundle:Basket:showStoredBasketPreview`	User menu: displays a badge with the number of products in stored comparison or the number of stored baskets	caching strategy `basket_preview` Purged when basket changes. Tags: `siso_basket_<basketid>`
`SilversolutionsEshopBundle:Navigation:showMenu`	Left menu	Tag: `siso_menu`
`SilversolutionsEshopBundle:Navigation:showMenu`	Main menu	Tag: `siso_menu`

Caching strategies are defined in configuration, see: HTTP caching.

Usage of cache tags¶

eZ Commerce uses cache tags to tag and purge content.

Tag	Used for	Purged
`siso_basket_<id>`	Basket preview in the header	By event, on basket change
`siso_menu`	Main menu and left side menus (product catalog)
`content-<contentid>`	Textmodules	When content (text modules) are changed
`siso_user_<userid>`	User-specific data (shows name of the user)	When the user logs in or out
