Ok that makes makes sense.

And yes it was started in the browser on a file upload from a form field.

I could use AJAX to load the file and then process it in the background
sending status points as it goes through AJAX.

I have done this is the past just not for so many steps to perform.

The more I read about the PHP buffer functions, I could not find a way
that would periodically send text without a header issue.

Guess why they have different tools for the different needs.

Thanks Str.
