You could use cfexecute to launch a wget at the command line. I have did this before. Make sure that you use the time out options in the wget statement so you do not get caught with hung wget threads
cfexecute allows you to launch the command and return to the page. The above method is not full proof because you do not know if the wget is successful or not. The cfexecute could call a script file that would do the wget, check to see the wget was successful and then issue another wget to call the cf page to do the call back and the rest of the processing.... -Randy ----- Original Message ----- From: "Andy Matthews" <[EMAIL PROTECTED]> To: "CF-Talk" <[email protected]> Sent: Monday, March 19, 2007 9:33 AM Subject: RE: downloading large files via cfhttp >I think you're probably asking for trouble.
