External caching on IBM HTTP Server

Restriction:

The Fast Response Cache Accelerator (FRCA) is available for both Windows NT and Windows 2000 operating systems and AIX platforms. However, the dynamic cache is only available on the Windows operating systems.
At the time of writing this redbook, afpaplugin.dll was not available for IHS2.0. This dll extends FRCA and enables the WAS to directly interface/access the FRCA, which is needed for dynamic caching on IHS.

WAS fragment cache can use the IBM HTTP Server as an external cache. We explain the appropriate configuration in this section. However, we were not able to test this scenario because our redbook sample configuration uses IBM HTTP Server 2.0 and afpaplugin.dll was not yet available for this version while writing this redbook.

The FRCA cache resides on the Web server node as shown in Figure 14-34.
