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

So doesn't this mean that "real-time" really means up to a 3 minute
delay?  In my case, I can't afford a 3-minute delay for up to date real
time data so I don't believe this would work for me.

while running CGI apps?

I have been using FRCA reverse proxy cache for the past year with cgi 
programs to serve election night results real-time.  I've got it set to 
cache for three mminutes, so the first call to a particular page loads 
it into the cache.  Subsequent calls during the next three minutes 
receive the cached copy.  There are literally thousands of pages cached 
in a large election and this works extremely well.

Prior to using the cache, each request did a cgi database read and buidl

of an html page, with a resulting high processor and disk usage.  We did

some stress testing originally and found a tremendous performance 
improvement using the cache, while keeping cpu usage within acceptable 
levels.  The real test will be next Tuesday night when the polls close. 
    Wish me luck!

BTW, the IE browser refresh button retrieves the cached copy.  Mozilla, 
however, forces a reload.  Fortunately, about 98% of our clients are IE,

so it works fine.
