This should be pretty simple to achieve. One of the restrictions with threads
is that a cfthread can not spawn another cfthread. So your going to need one
scheduled task that runs at a suitable interval. It will need to see if theres
a thread running and if not, kick off the first thread.

Hey folks - this is OT but I know someone on this list will know the answer:
I need to 'pre-load' a SWF file prior to it ever being launched with a

If limitations can be placed on uploading a single file and

That code is ran in a cfscript block.
You only have to create the object one. So the code would look

Hi,
We pre-announced the free offering of ColdFusion to educational institutions
for learning purposes at CFUnited. At CFUnited we mentioned that the formal
announcement and program launch would be a few months out. We were so excited
we couldn't wait to tell you. :) The offer isn't exclusive
Flex builder is, however, free for any use by any member of an
educational institution, so there's a difference. While I'd love to
see a similar program for CF, I suspect the CF policy will provide
only for teaching as has been discussed.

Yes. You add one or more instances to one or more servers. Then you define
a cluster, add the instances to it, and choose a load balancing algorithm.
You then associate that cluster with your IIS site (or apache virtual server
