Customize page cache behavior
Caching is essential for achieving the high levels of scaling and performance that many applications expect. The VIP Platform’s content delivery network (CDN) is a global network of edge servers that are set to default configurations and behaviors that maximize cache hit rates.
Response headers and the VIP Cache Personalization API can be leveraged by WordPress and Node.js applications to customize some of the default behaviors and responses of the page cache.
-
Vary HTTP response header
The Vary HTTP response header is respected for a limited set of values on the VIP Platform.
-
IP geolocation
The VIP edge cache respects a set of geolocation response headers that make it possible to deliver variations of cached content based on the end user’s global location.
-
Cache-control headers
The cache-control HTTP header specifies directives that control how browsers, CDNs, and proxies handle cached responses. In most cases, the cache-control header value for WordPress and Node.js applications can be set to custom response directives.
-
The VIP Cache Personalization API
The VIP Cache Personalization API allows a new cache group to be created and users to be assigned to specific segments within that group.
