Oh wise monks, I am hoping you can help me. From various posts on this site, I have figured out how to setup a fork. I am now trying to upload a large file from a web browser and display to the uploader some kind of status. I've implemented this using CGI::Ajax, but I need a way to do this without using javascript. Here is the code I have: 
#!/usr/local/bin/perl
$|++;

use CGI;
my $req = new CGI;

if (-f "temp.txt") {
 print "Content-type: text/html\n\n";
 print "done!\n";
 unlink("temp.txt");
 exit(0);
}

my $pid = fork();
if ($pid == 0) {
 print "Content-type: text/html\n\n";
 print "<META HTTP-EQUIV='Refresh' CONTENT='2'>\n";
 print "working...\n";
 exit(0);
} else {
 $file = $req->param("file");
 # yeah, I'll change this later
 open (OUTFILE, ">temp.jpg"); 
 while (my $bytesread = read($file, my $buffer, 1024)) { 
  print OUTFILE $buffer; 
 } 
 close (OUTFILE); 
 open(TEMP, ">temp.txt");
 print TEMP "fdas\n";
 close(TEMP);
 waitpid($pid,0);
}

The problem is that nothing is displayed until the file upload has completed, then the forking all works (it does the meta refresh and everything). There must be a way for the uploading to take place in the background, but I can't figure it out. Any help would really be appreciated!
