Sad that this even got 1 upvote. I tried to edit the KyleMit's answer but the forum was marking as a wrong indented code, even it wasn't, so I'm adding my contribution right bellow: As the question is tagged as a twitter-bootstrap topic and not only twitter-bootstrap-3 , maybe it's helpful to update the response for the newer version of Bootstrap.
Everything else remains the same on that case, except the lib version of course! Rocha 3 3 silver badges 16 16 bronze badges. Thanks to KyleMit. Anand Anand 1 1 silver badge 9 9 bronze badges.

Privacy policy. The Office CDN improves performance by caching static assets closer to the browsers requesting them, which helps to speed up downloads and reduce latency.
The Office CDN is composed of multiple CDNs that allow you to host static assets in multiple locations, or origins , and serve them from global high-speed networks. Depending on the kind of content you want to host in the Office CDN, you can add public origins, private origins or both. See Choose whether each origin should be public or private for more information on the difference between public and private origins. If you are already familiar with the way that CDNs work, you only need to complete a few steps to enable the Office CDN for your tenant.
This topic describes how. Read on for information about how to get started hosting your static assets. There are other Microsoft-hosted CDNs that can be used with Office for specialized usage scenarios, but are not discussed in this topic because they fall outside the scope of the Office CDN.
Head back to Network planning and performance tuning for Office Plan for deployment of the Office CDN. Before you deploy the Office CDN for your Office tenant, you should consider the following factors as part of your planning process. In general, CDNs are most effective for hosting static assets , or assets that don't change very often.
A good rule of thumb is to identify files that meet some or all of these conditions:. For example, small files that are repeatedly requested like site images and scripts can significantly improve site rendering performance and incrementally reduce the load on your SharePoint Online sites when you add them to a CDN origin. Larger files such as installation executables can be downloaded from the CDN, delivering a positive performance impact and subsequent reduction of the load on your SharePoint Online site, even if they are not accessed as often.
Performance improvement on a per-file basis is dependent on many factors, including the client's proximity to the nearest CDN endpoint, transient conditions on the local network, and so forth. Many static files are quite small, and can be downloaded from Office in less than a second. However, a web page may contain many embedded files with a cumulative download time of several seconds.
Serving these files from the CDN can significantly reduce the overall page load time. See What performance gains does a CDN provide?
The CDN fetches your assets from a location called an origin. You have great flexibility when you specify origins for your organization. For example, you can specify multiple origins or a single origin where you want to put all your CDN assets.
You can choose to have both public or private origins for your organization. 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. The CDN caches any chunks as they're received.
The entire file doesn't need to be cached on the CDN cache. Subsequent requests for the file or byte ranges are served from the CDN cache. If not all the chunks are cached on the CDN, prefetch is used to request chunks from the origin. This optimization relies on the ability of the origin server to support byte-range requests; if the origin server doesn't support byte-range requests, requests to download data greater than 8mb size will fail.
The default complete cache fill feature enables the CDN to pull a file into the cache when an initial request is abandoned or lost. Complete cache fill is most useful for large assets. Typically, users don't download them from start to finish. They use progressive download. The default behavior forces the edge server to initiate a background fetch of the asset from the origin server.
Afterward, the asset is in the edge server's local cache. After the full object is in the cache, the edge server fulfills byte-range requests to the CDN for the cached object. The default peer cache fill hot-filing feature uses a sophisticated proprietary algorithm.
It uses additional edge caching servers based on bandwidth and aggregate requests metrics to fulfill client requests for large, highly popular objects. This feature prevents a situation in which large numbers of extra requests are sent to a user's origin server.
