I also developed upload status capability for my company that works very similarly to yours. I am currently working on integrating the changes I made into a patch for 4.3.2 for members of this list to evaluate (I originally made the upgrade to 4.1.2).
I see you came to the same conclusion I did, that the easiest way to pass information seemed to be through the use of temporary files. I was hoping that once I submitted my patch that someone on this list might have a better suggestion like direction on using shared memory or something. --David -----=+=----- David Enderson Programmer Digital IMS 402.437.0137 [EMAIL PROTECTED] > Hi, > > To make a long story short, I needed an upload progress > metter, so the users will something while their huge files > are uploaded to the server.
