I've got this down to a bare bones test but am still stumped. Can anyone
explain why I get the behavior I do?
I have a frameset with 3 frames:
<html>
<head><title>testing</title></head>
<frameset rows='100,100,*'>
<frame src='test1.php'></frame>
<frame src='test2.php'></frame>
<frame src='test3.php'></frame>
</frameset>
</html>
test1.php and test2.php are both simply: <? sleep(5); ?>
test3.php is simply: <? echo "This is some content"; ?>
When I invoke the main frameset, the output from test3.php takes 5 seconds
to appear.
If I comment out either one of the sleep calls, the output from test3.php is
immediate, which is what I expected in the first place.
I have session.auto_start = 0 in php.ini, so this has nothing to do with
sessions.
I am running php 5.0.5.
I get the same results with both apache 2/mod_php and lighttpd/fastcgi, the
latter with 40 php processes running.
I thought that each frame in a page was executed independently and
asynchronously, yet frame4.php insists on "waiting" for one of the other
frames to complete (if the sleeps are 5 and 10, frame3 produces its output
after 5 seconds).
What am I missing here?
