Most organizations will choose to implement a combination of the two. You can create new container for your origins such as folders or document libraries, and add files you want to make available from the CDN. This is a good approach if you have a specific set of assets you want to be available from the CDN, and want to restrict the set of CDN assets to only those files in the container. You can also configure an existing site collection, site, library or folder as an origin, which will make all eligible assets in the container available from the CDN.
Before you add an existing container as an origin, it's important to make sure you are aware of its contents and permissions so you do not inadvertently expose assets to anonymous access or unauthorized users. CDN policies exclude assets in public or private origins by attributes such as file type and site classification , and are applied to all origins of the CdnType private or public you specify in the policy.
For example, if you add a private origin consisting of a site that contains multiple subsites, you can define a policy to exclude sites marked as Confidential so content from sites with that classification applied will not be served from the CDN.
The policy will apply to content from all private origins you have added to the CDN. Keep in mind that the greater the number of origins, the greater the impact on the time it takes the CDN service to process requests. We recommend that you limit the number of origins as much as possible. When you identify an origin, you specify whether it should be made public or private.
Access to CDN assets in public origins is anonymous, and CDN content in private origins is secured by dynamically generated tokens for greater security.
Regardless of which option you choose, Microsoft does all the heavy lifting for you when it comes to administration of the CDN itself.
Also, you can change your mind later, after you've set up the CDN and identified your origins. Both public and private options provide similar performance gains, but each has unique attributes and advantages. Public origins within the Office CDN are accessible anonymously, and hosted assets can be accessed by anyone who has the URL to the asset. Because access to content in public origins is anonymous, you should only use them to cache non-sensitive generic content such as JavaScript files, scripts, icons and images.
Private origins within the Office CDN provide private access to user content such as SharePoint Online document libraries, sites and proprietary images. Access to content in private origins is secured by dynamically generated tokens so it can only be accessed by users with permissions to the original document library or storage location.
Private origins in the Office CDN can only be used for SharePoint Online content, and you can only access assets in private origins through redirection from your SharePoint Online tenant. You can read more about how CDN access to assets in a private origin works in Using assets in private origins. You should never place resources that contain user information or are considered sensitive to your organization in a public origin.
If you remove an asset from a public origin, the asset may continue to be available for up to 30 days from the cache; however, we will invalidate links to the asset in the CDN within 15 minutes. This means that you can reference the location of background images and other objects relative to the location of the asset that's calling it.
While you can construct a public origin's URL, you should proceed with caution and ensure you utilize the page context property and follow the guidance for doing so.
The reason for this is that if access to the CDN becomes unavailable, the URL will not automatically resolve to your organization in SharePoint Online and might result in broken links and other errors. The URL is also subject to change which is why it should not just be hard coded to its current value. The default file types that are included for public origins are. You can specify additional file types. You can configure a policy to exclude assets that have been identified by site classifications that you specify.
For example, you can choose to exclude all assets that are marked as "confidential" or "restricted" even if they are an allowed file type and are located in a public origin.
Users can only access the assets from a private origin if they have permissions to access the container. Anonymous access to these assets is prevented. Assets in private origins must be referred from the SharePoint Online tenant. Direct access to private CDN assets does not work. If you remove an asset from the private origin, the asset may continue to be available for up to an hour from the cache; however, we will invalidate links to the asset in the CDN within 15 minutes of the asset's removal.
The default file types that are included for private origins are. Just like with public origins, you can configure a policy to exclude assets that have been identified by site classifications that you specify even if you use wildcards to include all assets within a folder or document library. Unless you specify otherwise, Office sets up some default origins for you when you enable the Office CDN. If you initially opt not to provision them, you can add these origins after you complete setup.
Unless you understand the consequences of skipping the setup of default origins and have a specific reason for doing so, you should allow them to be created when you enable the CDN. If you enabled the Office CDN prior to December , or if you skipped setup of default origins when you enabled the CDN, you can manually add this origin.
For more information, see My client-side web part or SharePoint Framework solution isn't working. Before you make changes to the tenant CDN settings, you should retrieve the current status of the private CDN configuration in your Office tenant. You can enable your organization to use public origins, private origins, or both at once. You can also configure the CDN to skip the setup of default origins when you enable it.
You can always add these origins later as described in this topic. For example, to enable your organization to use both public and private origins, type the following command:. To enable your organization to use both public and private origins but skip setting up the default origins, type the following command:. See Default CDN origins for information about the origins that are provisioned by default when you enable the Office CDN, and the potential impact of skipping the setup of default origins.
If you want to add additional file types to the list, use the cmdlet first to find out what file types are already allowed and include them in the list along with your new ones.
By default, common asset types are allowed, for example. If you want to exclude additional site classifications, use the cmdlet first to find out what classifications are already excluded and then add them along with your new ones. By default, no site classifications are excluded.
For example, you can exclude sites marked as Confidential so content from sites with that classification applied will not be served from the CDN. This depends on your tenant settings. You can define multiple origins. The value of path is the relative path to the library or folder that contains the assets. You can use wildcards in addition to relative paths. Origins support wildcards prepended to the URL.
This allows you to create origins that span multiple sites. For example, to include all of the assets in the masterpages folder for all of your sites as a public origin within the CDN, type the following command:. You can add an origin with a specific relative path.
You cannot add an origin using the full path. This example adds a private origin of the folder1 folder in the site collection's site assets library:. The following examples add a private origin of the folder 1 folder in the site collection's site assets library:. In private origins, assets being shared from an origin must have a major version published before they can be accessed from the CDN.
Once you've run the command, the system synchronizes the configuration across the datacenter. This can take up to 15 minutes. Normally, these origins are set up for you by default when you enable the Office CDN. However, if you want to enable them manually, follow these steps. For example:. Once you've set up the CDN, you can make changes to your configuration as you update content or as your needs change, as described in this section.
Once you've completed the setup steps, you can add new assets, and update or remove existing assets whenever you want. Just make your changes to the assets in the folder or SharePoint library that you identified as an origin.
If you add a new asset, it is available through the CDN immediately. However, if you update the asset, it will take up to 15 minutes for the new copy to propagate and become available in the CDN. You can remove access to a folder or SharePoint library that you identified as an origin. You cannot modify an origin you've created.
Instead, remove the origin and then add a new one. If you have both the public and private origins enabled for the CDN, you need to run the cmdlet twice as shown in the following examples. Connect to your tenant using PnP PowerShell:. You can enable your organization to use public origins, private origins, or both at at the same time. When you exclude site classifications by using the Set-PnPTenantCdnPolicy cmdlet, you overwrite the currently defined list.
The procedures in this section require that you have installed the Office CLI. Next, connect to your Office tenant using the login command.
You can manage the state of the Office CDN in your tenant using the spo cdn set command. To check if the particular type of Office CDN is enabled or disabled, use the spo cdn get command.
You should never place resources that are considered sensitive to your organization in a SharePoint document library configured as a public origin. Use the spo cdn origin add command to define a CDN origin. Where path is the relative path to the folder that contains the assets. Release files for older releases which have now reached end-of-life may have been signed by one of the following:. You can import a person's public keys from a public keyserver network server you trust by running a command like:.
On the version-specific download pages, you should see a link to both the downloadable file and a detached signature file. To verify the authenticity of the download, grab both files and then run this command:. Note that you must use the name of the signature file, and you should use the one that's appropriate to the download you're verifying. Want to contribute?
