Will Files Cached in Azure CDN be Rotated Out if not Frequently Accessed? RRS feed

  • Question

  • Hi,

    On Webhostingtalk, someone said "Depends on the CDN provider. Check those who can offer dedicated storage on the egde, otherwise yes - the content will be rotated out too quickly and the downloads may actually be slower." Therefore, I just wonder if the Azure CDN offers dedicated storage or not. Whether the infrequent files will be rotated out?

    Thanks

  • Hi, 

    You can refer this feature document: https://docs.microsoft.com/en-us/azure/cdn/cdn-features

    Microsoft Standard CDN doesn't support "Cache/header settings (using caching rules)" feature.

  • Hi, 

    You can choose to set no TTL on a file. In this case, Azure CDN automatically applies a default TTL of seven days, unless you've set up caching rules in the Azure portal. This default TTL applies only to general web delivery optimizations. For large file optimizations, the default TTL is one day, and for media streaming optimizations, the default TTL is one year.

  • Hi

    I read the article you provide. In this article, it said "Caching rules are available only for Azure CDN Standard from Verizon and Azure CDN Standard from Akamai profiles. For Azure CDN Premium from Verizon profiles, you must use the Azure CDN rules engine in the Manage portal for similar functionality.". However, it does not mention the Azure CDN Standard from Microsoft, should I also use Azure CDN rules engine as well?
