Hey monks,

I need to write a CGI program that flashes a message on the screen, while it does a big time-consuming process.

Prob is that the browser hangs, while the process is going, then flashes the message when it's all ended.

How can I get the code to flash the message, stop HTTP, and then continue with the big process?

I tried closing STDOUT after flashing the message, but that tends to terminate everything (which shouldnt, since after all I am closing standard output, but shouldnt close the program down.

Thanks!

Here's my code:

sub logmining'start
{    

    my ($xtract);
    my ($userEmail, $head, $foot, $myFile);
    my (@range);

    $head = &logmining'PrintHeader ();
    $foot = &logmining'PrintFooter ();
     
        # FLASH MESSAGE:
    print "$head<tr bgcolor=\"#EBEBEB\"><td><span class=\"texthead\">T
+he data is now being processed.  Once it is done, you will get an ema
+il with all the results that will be sent to $userEmail.</span></td><
+/tr>$foot";

    
    print STDERR "\n\n===== START =====\n";

    # Get range of dates
    @range = &logmining'getDateRange ();
    foreach $myFile (@range)    
    {
        # TIME CONSUMING PROCESS:
        print STDERR "gunzip -c $myFile | grep \"01225322|2199592\"\n\
+n";
        $xtract = `gunzip -c $myFile | egrep "01225322|2199592"`;
        last;  # JUST RUN ONE FOR NOW PLEASE!
    }
    print STDERR "XTRACT:\n$xtract\n\n";
    exit (1);
