Bulk Load Content

Submits a bulk load that defines the content that will be loaded. Loading content caches an asset on our edge servers. This allows that content to be served directly from the edge of our network to your users.

Key information:

• There is a default limit of 50 concurrent load requests at any given time. Exceeding this limit will generate a 400 Bad Request.

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

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

• An asset should only be loaded a single time per unique combination of platform and protocol.

  If a load request is limited to a specific region, then an asset should be loaded a single time per unique combination of platform, protocol, and region.

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

  • Loading via Load Content Endpoint: Get Load Request endpoint
  • Loading via Bulk Load Content Endpoint: Get Bulk Load Request endpoint

Request Body

Pass the following request body parameters:

Name	Data Type	Description
EdgeNodeRegionIds	Array	Defines the set of regions to which the bulk load request will be applied. Set this parameter to the desired region ID(s). Use a comma to delimit multiple regions. Regional loading is designed to meet specialized cache management needs. When in doubt, load content to all regions. Omitting this parameter will apply the load 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 loaded to our edge servers. Make sure to include the appropriate protocol (e.g., http://).
MediaType Required	Integer	Identifies the delivery platform to which assets will be loaded by its system-defined ID. Valid values are: 3: HTTP Large 8: HTTP Small 14: Application Delivery Network (ADN)
