Since version 1906 of Configuration Manager, it is possible to install a Microsoft Connected Cache server on distribution points. This functionnality has been renamed Microsoft Connected Cache with version 1910 of Configuration Manager. This server is a Transparent on-demand caching server for uploaded content through distribution optimization. It is possible to limit the use of this server using client settings. So it is easy to limit access to this feature only to the local Configuration Manager client.
How it works
When a client is configured to use this feature, the request made by the client is not made to the CDNs but to the cache server. The content is cached so that the server can respond to future requests from clients requesting the resource. In case caching is not yet enabled or the resource is not cached, the client will retrieve the sources directly from the Internet. The Distribution Optimization feature is used for downloading. This feature allows an optimization of the distribution.
- 1 – SCCM Client searches ressource and found the address of the CDN (content distribution network)
- 2 – Configuration Manager configure the parameters for optimizing the distribution to the customer. Thee client obtain the name of the cache server.
- 3 – Configuration Manager client A request ressource to the cache server.
- 4 – If the resource is not cached. Configuration Manager client download to the CDN (content distribution network)
- 5 – If the cache server does not reply. Configuration Manager client download to the CDN (content distribution network)
- 6 – Configuration Manafer use distribution optimisation for ressource
