What is Cache Path?
The idea behind Cache Path is to provide the end user to choose the source location and make it available across all the CDN nodes without calling the actual origin server. This data is then copied as cache on all the edge servers which will act as the origin for any request made by the customers from across all the globe.
By choosing the path and extension of the file, you can specify what items are to be cached and made available for the customer making request to connect to your site.
