<div class="important"><span class="importanttitle">Important:</span> Information

for this topic supports the latest PTF levels for HTTP Server for i5/OS .
|
|
It is recommended that you install the latest PTFs to upgrade to the latest
|
|
level of the HTTP Server for i5/OS. Some of the topics documented here are
|
|
not available prior to this update. See <a href="http://www-03.ibm.com/servers/eserver/iseries/software/http/services/service.html" target="_blank">http://www.ibm.com/servers/eserver/iseries/software/http/services/service.htm</a> <img src="www.gif" alt="Link outside Information Center" /> for more information. </div>

|
<p>The following explains how to enable FRCA, FRCA logging, and FRCA file
|
|
caching. See Fast Response Cache Accelerator (FRCA) for HTTP Server (powered
|
|
by Apache) for more information. </p>
|
|
<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>
