>In this case, does using FRCA add any benefit?

Look at the reverse proxy part of FRCA. It's not well documented (and I
haven't used it myself) but what I've seen seems to imply that the FRCA
can cache based on the URL. So, the first request for
http://www.whatever.com/item.jsp?ItemID=72 may have to make it's way up
to your CGI program, but the second and subsequent requests can get
served from the FRCA cache -- after all, has the page really changed?
Caching like this is a very powerful tool, but you have to be aware of
it in page design to make the best use of it. Some things are truly
dynamic, and caching isn't possible, while others appear to be dynamic,
but really aren't. 

For example, go to the iSeries home page and click on the "Conference"
box on the right. That's a dynamic page
(http://www-306.ibm.com/services/learning/ites.wss?pageType=page&content
ID=a0000716) but there's no good reason to go to the database everytime
someone looks at that page. This would be a great example of when to use
the FRCA (provided the # of hits warrant its use, 2 hits a day, who
cares, 2 million and the savings is significant)

Subject: [WEB400] FRCA-Fast Response Cache Accelerator any benefit while
running CGI apps?

My apologies for the continuous questions but now that I'm running
Apache, I
feel like a kid in a candy store and am looking to maximize my CGI
performance.  The documentation is useful but end user experience is
almost
always much more informative.

This question is about the FRCA.  My CGI apps are basically RPG database
intensive programs that don't make much use of the IFS.  About the only
IFS
references I use is for the graphics (icons and pictures) I store on the
IFS
so my CGI apps can reference them.

In this case, does using FRCA add any benefit?


Also, I see there are options to specify the min and max number of CGI
jobs.
The default is 40.  I cannot find any documentation on recommended
values
based on my system size.
