rflush problem
Hello
I trying to do something like this:
[+ hello +]
[-
$req_rec->rflush;
sleep 5;
-]
[+ hello again +]
... but it is not working. Does anybody know how to solve this problem ?

The setup looks ok.
If your sleep is inside a table or list, Embperl will flush this table not
before the end of the table (that's necessary to support dynamic tables).
Also your browser will not be able to display the table before it got it all
(because it need the to calc the layout)

The point is that Embperl is first processing the whole page and outputing
it afterwards (so you are able to set http headers, generate error messages
etc.). So at the point where you call rflush, nothing has been send to the
browser at all. To change this set optEarlyHttpHedears in your httpd.conf
(with EMBPERL_OPTIONS). With this option set, Embperl send the output
immediately and your above code will work. (at least with Embperl 1.x. 2.0
doesn't support optEarlyHttpHedears yet)
