How I can flush my cache contents, in order to pull the latest content from my origin?
You can do this by purging your CDN resource. To purge content:
1. Go to the CDN Resource menu.
2. Click your CDN Resource.
3. On the screen that appears, click the Purge tab.
4. In the input field insert paths on the CDN Resource. You may insert only one path per line. The maximum is 1000 lines
5. Click the Purge button.
It will take up to 5-10 minutes to reflect the changes.
Note: it is either purge one file per line, or click "full site purge" to purge all the cache in a CDN resource. For example, you are not allowed to purge all cache in a specific directory.
