Part of the problem, no doubt, is that communication with the web server is going thru an intermediate text file. That's how VFPCGI works. I had to add a special routine to upload binary data so it's probably something similar. You'd probably have more success creating a VFP COM mtdll and calling that from asp or asp.net. All the communication is thru COM. The added benefit is much better speed and scalability...
