Piping output to a web browser...

[Skip Hollowell]

A while back I saw a thread about keeping a web coonection alive (too bad I
saw it 4 hours AFTER I came up with the same general plan).  But I am still
struggling with how I can pipe the output to the screen on a streaming
basis.  The code I have seems to cache it all up and pushes it to the screen
all at once once I return out of the function.  Any ideas?

    print "Content-type: text/html"
    print
    sys.stdout.flush()
    print "<TITLE> Hello, World!</TITLE>"
    sys.stdout.flush()
    print "<PRE>Hello, World!"
    sys.stdout.flush()
    os.system ('date > /tmp/z.z')
    # This following routine takes a while to run but will delete the
/tmp/z.z file when it is done.
    os.system ('PATH=' + mypath + ';'  + support.ottestindexsitefile +
fFlags + ' >/tmp/x.x 2>&1 & ')
    sys.stdout.flush()
    while 1:
        try:
            #s = os.stat ('/tmp/z.z')
            f = open ('/tmp/z.z')
        except IOError:
            print "Process Done."
            break
        print ('Processing...')
        f.close()
        os.system ('sleep 2;date')
        sys.stdout.flush()
    os.system ('rm /tmp/z.z')

    return 'ZZZ'
