Hi. I am trying to write a (somewhat) long-running cgi script that
will display its
output as it processes.
Right now, my browser is waiting until receiving all the output (until
the script
terminates or closes stdout) before displaying anything.
Based on what I have read, content should be pushed to the client
whenever my script flushes stdout. For example this is what is claimed
at http://httpd.apache.org/docs/1.3/misc/FAQ-F.html#nph-scripts
I am using apache 2.2.4 on x64 Ubuntu.
Here is an example script in perl:
#!/usr/bin/perl
$| = 1;
print "Content-type: text/plain\n\n";
for ($i = 1; $i < 5; $i++)
{
print "$i\n";
sleep(3);
}
And in python:
#!/usr/bin/python
import time
import sys
print "Content-type: text/plain\n"
for i in xrange(4):
print i
sys.stdout.flush()
time.sleep(3)
In both cases, the client waits for script to finish before displaying
anything. Why?
