You could use cfx-http5 for this (http://www.cftagstore.com/tags/cfxhttp5.cfm). Options are:
1. The tag will not buffer file in memory. 2. You can do this asynchronously (not in CF thread), while executing another code on the same (or different) page. 3. You can check the status of the process in real time and to cancel it, if needed. 4. You can launch the job in a parallel separate (non-CF) thread, but result will be unknown until the file appears (or not). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| ColdFusion MX7 by AdobeĀ® Dyncamically transform webcontent into Adobe PDF with new ColdFusion MX7.
