Bulk Purge Content

Submits a bulk purge that defines the content that will be purged. Purging content invalidates the cached version of an asset from our edge servers. By default, the CDN will forward the next request for that content to the origin server.

Key information:

• There is a default limit of 50 concurrent purge requests. Exceeding this limit will generate a 400 Bad Request.

  All outstanding purge requests count towards this concurrent purge request limit. This includes purge requests submitted via the MCC, the Purge Content endpoint, or the Bulk Purge Content endpoint.

  With regards to bulk purges, each specified URL counts as a separate purge request. For example, each element defined in the MediaPath array of the Bulk Purge Content endpoint counts as a separate purge request.

• An asset should only be purged a single time per platform. The asset will be purged for all CDN and edge CNAME URLs that point to the purge location, regardless of the protocol (i.e., http or https) used to reach it.

  If the purge request is limited to a specific region, then an asset should be purged a single time per unique combination of platform and region.

• An asset only needs to be purged a single time per unique combination of platform and region. The asset will be purged for all CDN and edge CNAME URLs that point to the purge location, regardless of the protocol (i.e., http or https) used to reach it.

• A short period of time may elapse before an asset is completely purged from our entire network. However, a successful request will immediately return an ID in the response. Find out the current status of your purge request(s) by passing this ID to:

  • Purging via Purge Content Endpoint: Get Purge Request endpoint
  • Purging via Bulk Purge Content Endpoint: Get Bulk Purge Request endpoint

Request Body

Pass the following request body parameters:

Name	Data Type	Description
EdgeNodeRegionIds	Array	Defines the set of regions to which the specified purge request(s) will be applied. Set this parameter to the desired region ID(s). Use a comma to delimit multiple regions. Regional purging is designed to meet specialized cache management needs. When in doubt, purge content from all regions. Omitting this parameter will apply the purge request to the entire network (i.e., all regions). View example. JSON: EdgeNodeRegionIds: [3,4], XML: <EdgeNodeRegionIds> <int xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">3</int> <int xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">4</int> </EdgeNodeRegionIds> Retrieve a list of platform-specific regions and their corresponding system-defined IDs through the Get Load/Purge Regions endpoint. Although the response for the Get Load/Purge Regions endpoint includes the POPs (i.e., edge nodes) associated with each region and their system-defined IDs, the EdgeNodeRegionIds request parameter only accepts the system-defined IDs for load/purge regions.
MediaPath Required	Array (String Values)	Identifies each CDN or edge CNAME URL that will be purged from our edge servers. Include the protocol (e.g., http://) when specifying each URL. More information on purging (including syntax information). For the purpose of this endpoint, the http:// and https:// protocols are interchangeable.
