What I expected to see was the word 'Started' displayed in my browser, followed by a 5 second delay, and then see the word 'Done' displayed.

What I get is a 5 second delay and then both 'Started' and 'Done" appear at the same time.

Any ideas as to what I am doing wrong?

Just ensure that you finish each chunk with \n A call to flush() may be useful too: <dtml-call "RESPONSE.write('Starting\n')"> <dtml-call "RESPONSE.flush()"> That should work fine. BTW, there is no need to set those headers more than once. Gabriel Genellina Softlab SRL
