the file, extracted the data, used <CFQUERY> to update a database, and then
deleted the file. I manually refreshed the page to show that the next SELECT
statement pulled all the data, including the one just auto-inserted.
So no, your #3 was not what I used, and is not something that Blackstone
will directly facilitate. But, if you have a way to do that now (perhaps
using Flash on the client and Flash Comm Server, as one example) then sure,
it'll work.

What I was wondering is:
1) Was there a browser request pending for CF Template & the server
event satisfied the request (Pull)
2) Was there an autorefresh in the page that made a server request
every n seconds (Pull)
3) Did the server send an unsolicited page to an idle browser (Push)
I know how to do 1 and 2, but am hoping that Blackstone will support 3.
You would likely need to authorize the server to send unsolicited
requests, to the browser(s).
But this opens up some interesting possibilities:
-- Real-time status monitoring
-- Efficient chats/whiteboards/collaboration
-- Streamers
-- Motion detectors & alarms
Maybe Ben will need to answer this.
TIA
