#  Caching

The [VIP Platform’s infrastructure](https://docs.wpvip.com/vip-platform/) includes
several caching layers to enhance site performance.

 * 
   ### 󠀁[Page cache](https://docs.wpvip.com/caching/page-cache/)󠁿
   
 * The page cache is the first level of caching that is encountered by each request
   made to a WordPress or Node.js environment on the VIP Platform. Responses from
   origin are cached at VIP’s global network of edge cache server locations for 
   future requests.
 * 
   ### 󠀁[Object cache](https://docs.wpvip.com/caching/object-cache/)󠁿
   
 * The WordPress object cache is the second layer of caching that is encountered
   by requests that pass through the page cache and are routed to the origin servers.
   The object cache stores common or expensive operations directly into memory so
   that subsequent requests can quickly access them.
 * 
   ### 󠀁[Query cache](https://docs.wpvip.com/caching/query-cache/)󠁿
   
 * The Query Cache provides light-weight and transparent in-memory caching of many
   database queries (such as post lookups) which reduces the overall load on the
   database and results in a faster, more-scalable site.
 * 
   ### 󠀁[Static asset caching](https://docs.wpvip.com/caching/static-asset-caching/)󠁿
   
 * Static assets for WordPress and Node.js environments are cached and served by
   VIP’s edge cache servers.
 * 
   ### 󠀁[Uncached functions](https://docs.wpvip.com/caching/uncached-functions/)󠁿
   
 * Some functions in WordPress Core are purposely uncached, and will always result
   in an SQL query when called. This can have performance implications for a site.
