You can use the Cache Server provided by SAP (see also Cache Server) in conjunction with third-party content servers to cache documents while they are being read accessed.

From release 4.6B, you can use the SAP Content Server (see SAP Content Server) in conjunction with a cache server (see also note 216419, Multi-Level Caching and Content Server Proxies).

To allow you to use signed URLs between the SAP Content Server and the cache server, the Content Server component of the SAP Content Server HTTP Interface has been extended. To differentiate the new extended version from the previous version (version 4.5 or 0045), the new version is called version 4.6 or 0046.

If you want to use a third-party content server in a heterogeneous environment consisting of SAP Content Server, SAP’s own cache server, and a third-party content server, the third-party content server needs to be enhanced so that it supports all SAP Content Server HTTP Interface commands. The new command getCert must also be implemented so that the requirements for the new version of the interface are fulfilled.

For further information, see the documentation on the Content Management Service in the SAP Library in the sections Knowledge Provider and Caching, Cascaded Caches, and Content Server Aliases. You can also get information from the SAP Integration and Certification Centers.
