Shows a lengthy shell process with Apache

I have a CGI script that takes about 1 minute. Now Apache returns results only to the browser after the process is complete.

How can I make it show output as it was running on the terminal?

Here is an example that demonstrates the problem.

I want the numbers 1 through 5 to be displayed when they are printed.

I had to disable mod_deflate so that chunk mode works with apache

I have not found another way for my cgi to turn off automatic encoding for gzip.
