Abstract: Edge server cache techniques are described to prepopulate an edge server cache. The edge servers are configurable to maintain a first set of digital content that is currently made available via content requests to client devices. The edge servers are also configured to maintain a second set of digital content, separately, that is to be launched. The second set of digital content is not made publicly available until launch, but rather is “pre-warmed” in the caches of the respective edge servers. In an implementation, prelaunch access is provided using respective credentials, e.g., to verify operation of the second set of digital content using software and hardware resources at actual edge servers that implement the caches.
