Manually add .intunewin files to cache

It would be a great help if there was an option to manually add .intunewin files to MCC.

If an app is being updated and there's 50 receiving devices, they will still attempt to download individually because MCC won't cache the update until there's at least 3 (?) requests. The MCC server would start downloading later than the clients therefore missing its objective. On a satellite connection, that is not helpful.

    Thanks for the reply Andy, the workaround would be useful but the URL is unknown. Can you advise what the CDN URL should be for a particular app & intunewin package, assuming it only downloads the intunewin package.

    Example would be http://MCCIPAddress/filestreamingservice/files/INTUNE-APP-ID/packagename.intunewin?cacheHostOrigin=dl.delivery.mp.microsoft.com

    I have tried the above URL without success, it works when using the Microsoft.png file.

    Hey marty5, Sorry you are experiencing this issue of the 3 requests for Intune content, that's due to the VARY header being sent from the CDN which tells web servers not to cache the content. We have no control over this. The only workaround/pre-cache technique available today is to make the content request 3 times with a device or if you have the download URL you could force the cache.

    Example: if the request URL from CDN is this --> http://dl.delivery.mp.microsoft.com/filestreamingservice/files/7bc846e0-af9c-49be-a03d-bb04428c9bb5/Microsoft.png

    Request from cache using this URL --> http://MCCIPAddress/filestreamingservice/files/7bc846e0-af9c-49be-a03d-bb04428c9bb5/Microsoft.png?cacheHostOrigin=dl.delivery.mp.microsoft.com
