Purging Cached Manifest Files and File Chunks

Applies To:

HTTP LargeThis platform has been optimized to cache and deliver static content (e.g., HTML, CSS, JavaScript, ISO, multimedia, and software downloads, etc.) over HTTP or HTTPS.

Smooth StreamingThis feature allows dynamic streaming for live and on-demand content over the HTTP Large platform to Silverlight players. Our live streaming solution may be transmuxed to provide support for iOS devices.

The manifest file and the file chunks associated with a particular live smooth stream can be purged from all of our POPs. This means that the cached version of those files will be permanently deleted from our edge servers. All future requests for those files will cause our edge servers to forward the request to the origin server, which will either be an ingest point on our CDN or your own IIS origin server. Since all file chunks will have been purged from our CDN, DVR playback will not be available for the time frame covered by those files.

You can purge an entire live smooth stream from our CDN. This means that the client manifest file and the requested file chunks will be purged from all of our POPs worldwide. The proper purge URL that you should use depends on whether you are using a CDN or an IIS ingest point.

Please select the purge URL that applies to your configuration.

Base Purge URL for a CDN Ingest Point:
http://wpc.xxxxThis term represents your CDN account number which can be found in the upper right-hand corner of the MCC..{Base Domain}/21xxxxThis term represents your CDN account number which can be found in the upper right-hand corner of the MCC.
Base Purge URL for an IIS Ingest Point:
http://wpc.xxxxThis term represents your CDN account number which can be found in the upper right-hand corner of the MCC..{Base Domain}/80xxxxThis term represents your CDN account number which can be found in the upper right-hand corner of the MCC./CustomerOrigin

The CDN URL path that should be appended to the above path is noted below.

Purge path for a CDN Ingest Point:
/StreamName.isml/*
Purge path for an IIS Ingest Point:
/Path/StreamName.isml/*

The term Path represents the path to the folder that contains your Live Smooth Stream publishing point definition file. For example, if an edge CNAME points to the IIS virtual directory and the Live Smooth Streaming publishing point definition file is located in a subfolder called "My_Streams," then you should use the following CDN URL path: /My_Streams/StreamName.isml/*.
