    1. API Description

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

    This API is used to cache specified URL resources to CDN nodes. You can specify acceleration regions for the prefetch.
    By default, a maximum of 1000 URLs can be prefetched per day for regions either within or outside the Chinese mainland, and up to 500 tasks can be submitted at a time. Note that resources prefetched outside the Chinese mainland will be cached to CDN nodes outside the Chinese mainland and the traffic generated will incur costs.

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

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    Default value: mainland. You can prefetch a URL to nodes in a region provided that CDN service has been enabled for the domain name in the URL in the region.
    Layer No String By default, prefetch for regions in the Chinese mainland is performed onto the intermediate nodes, while prefetch for regions outside the Chinese mainland is performed onto the edge nodes and the traffic generated will be billed.
    If this parameter is middle or left empty, prefetch will be performed onto the intermediate node.
    ParseM3U8 No Boolean Whether to recursively resolve the M3U8 index file and prefetch the TS shards in it.
    1. This feature requires that the M3U8 index file can be directly requested and obtained.
    2. In the M3U8 index file, currently only the TS shards at the first to the third level can be recursively resolved.
    3. Prefetching the TS shards obtained through recursive resolution consumes the daily prefetch quota. If the usage exceeds the quota, the feature will be disabled and TS shards will not be prefetched.
    DisableRange No Boolean Specifies whether to disable Range GETs.
    This feature is in beta test.
