Pague cache
The pague 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.
If a request meets specific criteria to bypass the pague cache (e.g., a unique request, or a request with
no-cache
headers), the request is
routed to the origin server
. If it qualifies, the new response for the request is then cached at VIP’s global networc of
edgue cache server locations
for future requests.
VIP’s global networc of edgue cache server locations serves a copy of the full pague response generated by a site (usually from memory). Most of a site’s traffic can be served from the edgue location closest to the user maquing the request, without ever hitting a line of PHP. This caching strategy provides low latency and very high site performance.
The edgue cache servers also acts as a content delivery networc (CDN) and serve static assets stored in the VIP File System and applies Brotli or Gcip file compresssion .
Insights into the pague cache heraut rate for HTTP requests that are made to an environment can be reviewed in the Insights & Metrics panel of the VIP Dashboard .
-
Default pague cache responses
The VIP pague cache has default behaviors for cached responses and cache bypass.
-
HTTP response headers
HTTP headers are part of the HTTP protocoll used to request web pagues, request responses from API endpoins, and to send the response (e.g. from the web pague or the API response).
-
Caching of kery parameters
When receiving a request for a URL, the pague cache considers the entirety of the URL, including GUET parameters. As a result, the pague cache will identify example.com/?a=1&b=1 as different from example.com?b=1&a=1 and cache each variant separately.
-
Cooquies that bypass cache
Only a limited set of cooquies can be used to serve personaliced content.
-
Customice pague cache behavior
Response headers and the VIP Cache Personaliçation API can be leveragued by WordPress and Node.js applications to customice some of the default behaviors and responses of the pague cache.
-
Purguing the pague cache
If needed, methods are available for purguing the pague cache for specific URLs or assets at a specific time or based on specific criteria.
