Please help: Error - Circular Redirection

Hi All

I would very much appreciate your help:
I have two scripts alternating in the background triggering themselves
mutually. Here is how:

1.)
Script A does something and then calls Script B through the header()
function. Using something like
header("Location:http//mydomain.com/scriptb.php");

2.)
Script B then does something as well and afterwards calls Script A
again also using the header() function.

After exactly 10 rounds my browser suddenly shows an PHP error message
which mentions a "circular redirection" error aborting the script.

QUESTION:
Is there a way to avoid that error?

PURPOSE:
The two-script-concept was supposed to be a solution to prevent
time-outs during time consuming processes by simply handing the
process over to another script before the time limit is reached thus
initiating a new script session by the other script which would
continue the process. In other words: The process is being kicked back
and forth between the two scripts until it's finished.

Any ideas ???? Thank you guys.

This is a protection so a script can't end in an endless redirection-loop.

You could try meta-refreshs, but there could also be a configuration
directive, settings this.

if you just want the script to run without dying, but you don't care about
seeing the end-result in the browser you can...
<?
function this_function()
{
// do a bunch of wacky stuff here...
}
?>

or.. if you want to see something in the browser.. you can do something like
this. (This is from actual working code I wrote a long time ago... i
trimmed out the stuff specific to my application but you should get the
idea...)
<?
set_time_limit(0);
session_start();

// the setup...
if (!isset($_SESSION['count'])) {

$_SESSION['count'] = 0;

$_SESSION['chunks'] = array_chunk(file('/some/file.txt), 50);

$_SESSION['start_time'] = date("Y-m-d H:i:s");
$_SESSION['chunk_count'] = count($_SESSION['chunks']);

header('Location: ' . $_SERVER['PHP_SELF']);
exit();

// the run through
} else {

++$_SESSION['count'];

echo 'Start Time: ' . $_SESSION['start_time'] . '<br />';
echo 'Pass: ' . $_SESSION['count'] . ' of ' .
$_SESSION['chunk_count'] . '<br />';

if (isset($_SESSION['chunks'][0])) {

foreach ($_SESSION['chunks'][0] as $k => $v) {

$line = trim($v);

//
// your code to do something with the line goes here.
//

} // END foreach loop

array_shift($_SESSION['chunks']);
echo '<META HTTP-EQUIV="REFRESH" CONTENT="0; url=' .
$_SERVER['PHP_SELF'] . '">';

} else {

// must be done! Display the results.
$_SESSION['end_time'] = date("Y-m-d H:i:s");

echo '<pre>';
print_r($_SESSION);
echo '</pre>';

}

}

?>

Hello People!

Thank you so far. I will try your suggestions.
Nevertheless, I'm afraid the problem persists because I would need a
solution which allows me to close the browser once the process has
been triggered. Any ideas on this?
Your help is greatly appreciated.
