HTTP pull

OnApp CDN enables HTTP pull, push and caching for web content. With HTTP pull, content is pulled to an end user's closest CDN location when they request it, and is then available locally to other users that request it. Otherwise it stays on the origin server - the server that 'owns' the content. It's best suited for smaller file sizes, where the time taken to retrieve the original file from the origin server, for the first users in each location, will not be particularly noticeable. Once there's a local copy, local users will be served that copy until it changes.

Web content – push

With HTTP push, content is automatically distributed or 'pushed' to a selection of CDN locations when it is added to the origin server, or when it changes. It's better suited to larger files like software installers and patches, and when files are typically 50MB or larger - files that would take end users longer to download from the origin, if there isn't a local copy of the latest version.

Web content – caching

OnApp CDN also supports static and dynamic HTTP content caching at any CDN location. HTTP caching offloads web content onto the CDN network, and ensures that content is delivered more quickly by storing a copy at each CDN location.

Video on Demand

OnApp CDN allows you to deliver video files on request with YouTube-like control over playback, using features such as fast forward or rewind, and have the video buffer from that point instead of having to wait for video to download as with normal progressive streaming. Playback is up to 1080p. This protocol uses Nginix to serve videos through normal HTTP, supporting...

Reporting & analytics

OnApp CDN includes a range of reports that help you and your customers understand how different content and locations are performing. You can display reports as graphs and tables and export as a CSV for further analysis. CDN statistics can be viewed by CDN protocol type (HTTP Pull, Video on Demand etc); data type (cached and non-cached); by specific edge servers and groups of edges; by owner, country and time period; for live streaming and concurrent usage of live video streams; for CPU usage per edge and storage server; and for billing statistics.

Security

• - SSL support (vanity and shared certificates) from the origin to the CDN, and from the CDN to the end user
• - Link encryption for Flash (RTMPS, RTMPE, RTMPTE) to protect against content intrusion, unauthorized diversion and stream ripping
• - Secure Token support against spoofing/stream interceptors
