In Embperl 1.3 you can write
[- $dbgFlushOut = 1 -]
In Embperl 2 there is no way to flush buffers before everything is done.
What I do is to add a <meta equiv="refresh" content="3;....."> which will
refresh the page any n seconds and display a status. Of course in this case
you need to run your task in background.
The other possbility is to display a text like "Please wait..." and do a
meta refresh at the _end_ of the page with time 0. On the page you load yo
do no output and run your long task. The browser will display the previous
page until it sees new output.
