1. API Description

Domain name for API request: teo.tencentcloudapi.com.

When there are resources updated on the origin with the TTL remaining valid, users cannot access the latest resources. In this case, you can purge the cache using this API. There are two methods:

Delete: This method deletes the node cache without verification and retrieves the latest resources from the origin when receiving a request.

Invalidate: This method marks the node cache as invalid and sends a request with the If-None-Match and If-Modified-Since headers to the origin. If the origin responses with 200, the latest resources are retrieved to be cached on the node. If a 304 response is returned, the latest resources are not cached on the node.

For more details, see [Cache Purge](https://www.tencentcloud.com/document/product/1552/70759?from_cn_redirect=1).

A maximum of 20 requests can be initiated per second for this API.

We recommend you to use API Explorer
