keep alive refresh

Hello, I looked for some old questions about my problem in the m.l. archive but I did not find anything. I'm writing a php script which takes a couple of values from the web interface and then passes these values to a program which writes it's output on a file. Then the output of the file is published on the web page. The problem is that this program may take 1 minute up to 1 hour to write all the output on the file and the browser times out. Any suggestion on how to solve this? Many thanx Mauro
