The SPS uses reverse proxy architecture to enable access control, single sign-on, and SSL acceleration. It does not provide the content caching and some other features provided by traditional reverse proxy servers. The SPS is intended to be an addition to enterprise architecture, rather than a replacement for other proxy technologies. As such, the SPS can be placed in clusters with load balancing devices and caching devices on either side of the clusters.
The following illustration shows how the SPS can be inserted into a network to work in conjunction with load balancing devices.
Note: In addition to load balancing devices, caching devices can be placed on either side of the SPS cluster.
