I think the problem here is that, by the time CF could read the
Content-Length HTTP request header, it's too late - the browser
has sent the
file within the HTTP request body, and the web server has already received
it.
Before the CF engine receives an HTTP request to process, that

The thing I don't get is why CF couldn't look at the length parameter in the
HTTP header, and terminate the request if it doesn't like it... or does only IIS
get access to that before the whole HTTP request has gone through?
Theoretically, I imagine CF could start processing a request before the

your question. I've battled with project managers about this because
they want to be able to somehow assure a client that there is NO way
you can upload a file greater than a certain size. And like the guys

I have a different question about the method CF uses for file transfers on
Windows NT.
When I copy over a network, I know Windows NT reads the file to the computer
initiating the command and then copies the file to the destination. Does
CFFILE on NT do the same thing?
Also, does CFCONTENT read

ColdFusion has no way of knowing what the file size is BEFORE it reaches the
server. The way i've done it is allow the full file to be uploaded, check
the file size (CFFILE) and then delete it. Of course, the system will warn
the user that the file they uploaded was too big AFTER CF has checked
No. CF doesn't see the file until AFTER it's moved to the server

file being fully uploaded on the computer? please reply soon!

I wish they would have built that into the
no, not unless the user inputs the file size. CF resides on the server,
there's no way for it to "look at" the client machine.
