Hi All

How can I produce an output to the browser and let the script continue
to work in the background, producing a later screen output?

Example:
Trigger a database search so that the user immediately sees a
"...searching..." screen while the script actually searches and later
on outputs the result.

I always get a "header already sent" error.

Your help is greatly appreciated.
Jerry.
