Invalidate the CDN cache using Dynamic Media Classic invalidating-your-cdn-cached-content
The CDN (Content Delivery Network) caches Dynamic Media assets for fast delivery. However, when you make updates to an asset, those changes occur immediately. Invalidating your CDN cached content lets you quickly update assets that Dynamic Media delivers, instead of waiting for the cache to expire.
To invalidate your CDN cache using Dynamic Media Classic:
-
Open the Dynamic Media Classic desktop application, then sign in to your account.
Adobe provided your credentials and sign-in details at the time of provisioning. If you do not have this information, contact Customer Support.
-
Go to Setup > Application Setup > General Settings.
-
On the Application General Settings page, under the Servers group heading, locate the CDN Invalidation Template text box.
-
Specify the template that is used for invalidating the CDN (Content Delivery Network) cache.
For example, suppose you enter an image URL (including image presets or modifiers) referencing
<ID>, instead of a specific image ID as in the following example:https://server.com/is/image/Company/<ID>?$product$If the Template contains
<ID>, then Dynamic Media fills inhttps://<server>/is/imagewhere<server>is the Publish Server Name that is defined in General Settings and <ID> is the assets selected to be invalidated. -
In the lower-right corner of the page, select Close.
-
In the Dynamic Media Classic (Scene7) UI, select one or more assets, then go to File > Invalidate CDN. You see a list of one or more URLs generated from the template you created and the assets you selected. It uses the server URL listed under “Published Server Name” in the Application General Settings.
For example, with the CDN Invalidation Template set in the previous step, suppose you selected a single image asset named
Backpack_B. When you go to File > Invalidate CDN, it generates the following URL in the CDN Invalidation user interface:https://server.com/is/image/Company/Backpack_B?$product$ -
In the URL list box, select Continue to clear the cache for each specific URL. You can edit a URL or you can add a URL by typing or pasting it into the URL list box; you do not need to set the CDN Invalidate Template beforehand.
After you select Continue, an indicator displays an estimate of how long it takes to clear the cache.
If you selected multiple assets, then went to File > Invalidate CDN, each asset is referenced in the saved Template URL. Therefore, you can define a CDN Invalidate Template referencing each URL image preset that is referenced on your website such as product detail and search results. Then, when you select one or more images for invalidation from cache, the URLs automatically populate the interface.
note NOTE When you select assets, and then go to File > Invalidate CDN, Dynamic Media uses an invalidate CDN template to automatically create URLs to invalidate from the CDN. If there is nothing in the CDN Invalidate Template text box, then you get a blank URL list. Caching at the CDN is not asset-based; it is URL-based. Therefore, it is necessary to be aware of the complete URLs that are on your website. After you determine those URLs, you can add them to the Invalidate CDN Template text box earlier in the steps. Then, you can select those assets, and invalidate the URLs in one step. Another option is to add complete URLs to the Invalidate CDN list. If you follow this approach, it is unnecessary to select assets in Dynamic Media Classic before going to the File > Invalidate CDN option.
