The CenturyLink® Caching and Download service gives you a flexible and cost-effective solution to deliver your digital content to web users across the globe.
Note: Media portal is moving to a new help system. If you are reading this message, you have landed on the new help. Each month, we will migrate more and more content from our legacy system to this new platform. This new platform includes help for other portals and products (which you may also use), so your search results will show articles for topics beyond Media portal. To help you find the content you need, avoid broad searches. Upgrading to a new system will position us to offer a better experience to our users once we have migrated all content. We appreciate your patience during this time of transition.
Configurations tell the CenturyLink CDN (content delivery network) what to do when it receives requests for your content. You use definitions, properties, and match rules to build a configuration. Then, you promote the configuration to an environment to activate it.
Service-wide definitions are collections of common configuration data that can be referenced and that influence system behavior. Examples of definitions are a geo region or IP group. In and of itself, a definition does not influence how the system processes requests. Using definitions helps you avoid having to repeat common tasks across multiple match rules. You manage them in a single list allowing for a single change to propagate through all references.
Match rules are the core of the configuration. They provide the criteria for evaluating requests and responses and, when matched, specify one or more actions (e.g., setting cache expiration, calling geo definitions, content/header processing modes, etc.) for the system to take. Criteria-based settings are applied only if the specified criteria (a path) is met.
Prior to creating an HTTPS property, you’ll want to upload your certificate. Using Media portal, you can also generate a certificate signing request (CSR) you'll use to submit to your certificate authority.
