<p>The following explains how to enable FRCA, FRCA logging, and FRCA file

|
caching. See Fast Response Cache Accelerator (FRCA) for HTTP Server (powered

|
<p>FRCA is a Web cache architecture that is tightly integrated with the TCP/IP
|
||
|
|
stack. FRCA moves performance critical TCP Application functions into a fast
|
||
|
|
response cache that improves HTTP Server performance. </p>
