I've found cf flush to be useful when you are serving up long tabular report data. If you are going to output several
hundred rows, cfflush can help a lot. One approach I've used that works great for intranet sites where the browser is a
known item is a combination of a status bar, _javascript_ and cfflush. I create a flash movie that has a status bar with
frames from 1 to 100 (1 being an "empty" bar and 100 being "filled") based on a variable I can set using the
"SetVariable( )" function in _javascript_. Then, as I'm outputting data I increment that variable using cfflush and
_javascript_.
For example, using MOD 100 (or whatever threshold makessense to you) and currrent row I could run a calculation that
gives me the percent commplete of the output. let's say 13 percent at row 200. Then, I would write this:
(<script>movie.SetVariable(13,"13%");</script>) .. the first item is the frame number I want the movie to go to and
stop, the second variable is a label. I use <cfflush> to send it to the html page where it is run "inline" immediately.
The result is a nice looking status bar that climbs incrementally at the top of the report and lets the user know that
data is being sent to the browser and to please be patient. This approach can be useful for things like data upload
tools where user uploads a spreadsheet or database that is subsequently inserted into a table or appended to a file.
That's my 0.02.

Subject: CFFLUSH Advantages / Disadvantages
CF 4.5.1 and 5.0
Any opinions on the use of CFFLUSH? From my understanding you have to deal
with some tradeoff, e.g., it imposes several restrictions on the use of
other tags and the method of client variable storage. The upside is not so
clear, other than CFFLUSH help avoid time outs on slow Web sites?
Thanks,
