CakePHP XAMPP Internet Explorer теряет сессию через 10 секунд

после заполнения входов в представлении и нажатия кнопки отправки записи сохраняются очень хорошо, если я использую Firefox.

То же самое касается IE, если я достаточно быстр. Но когда я жду 10 секунд, данные POST, кажется, не достигают контроллера, я получаю это сообщение об ошибке

Notice (8): Undefined index: Incident [APP\Controller\IncidentsController.php, line 91]
Notice (8): Undefined index: Machine [APP\Controller\IncidentsController.php, line 93]Code
Notice (8): Undefined index: Machine [APP\Controller\IncidentsController.php, line 94]Code

$ this-> request-> data пусто

Это происходит только с IE.

Контроллер метод:

/**
* c_add method
*
* @return void
*/
public function c_add() {
if ($this->request->is('post')) {
$this->Incident->create();
$machineId = $this->Incident->Machine->find('first', array('conditions' => array('Machine.name' => $this->request->data['Incident']['machine_id_scancode'])));
$this->Incident->set(array(
'machine_id' => $machineId['Machine']['id'],
'costcenter_id' => $machineId['Machine']['costcenter_id'],
'inc_start' => date('Y-m-d H:i:s')
));
if ($this->Incident->save($this->request->data)) {
$this->Session->setFlash(__('The incident has been saved.'));
return $this->redirect(array('action' => 'c_index'));
} else {
$this->Session->setFlash(__('The incident could not be saved. Please, try again.'));
}
}
$machines = $this->Incident->Machine->find('list');
$products = $this->Incident->Product->find('list');
$incidentClasses = $this->Incident->IncidentClass->find('list');
$costcenters = $this->Incident->Costcenter->find('list');
$problemTypes = $this->Incident->ProblemType->find('list');
$problemCauses = $this->Incident->ProblemCause->find('list');
$specialists = $this->Incident->Specialist->find('list');
$this->set(compact('machines', 'products', 'incidentClasses', 'costcenters', 'problemTypes', 'problemCauses', 'specialists'));
}

Посмотреть:

<?php $this->extend('/Common/customer'); ?>
<div class="incidents form">
<?php echo $this->Form->create('Incident'); ?>
<fieldset>
<legend><?php echo __('Add Incident'); ?></legend>
<table>
<tr>
<td><?php   echo $this->Form->input('machine_id_scancode'); ?></td>
<td><?php   echo(__('</br>Choose Machine by starting to type and pick one from the list. </br> If your machine is not on the list, pick the "Common" entry for your Team, e.g. "Allgemein PPT"')); ?></td>
</tr>
<tr>
<td><?php echo $this->Form->input('customer_email'); ?></td>
<td><?php   echo(__('</br><p id="emailDescription">Email adress for job progress notification. Change as you like.</p>')); ?></td>
</tr>
<tr>
<td><?php echo $this->Form->input('inc_desc'); ?></td>
<td><?php   echo(__('Please describe what should be done.')); ?></td>
</tr>
<tr>
<td><?php echo $this->Form->input('product_id', array('empty' => true)); ?></td>
<td><?php   echo(__('Optional: Choose which product is affected.')); ?></td>
</td>
</table>
</fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
</div>
<script>
$(function() {
$("#IncidentMachineIdScancode").autocomplete({
source: "/stoerungen/machines/index.json"});
});
$(document).ready(function() {
$.ajaxSetup({cache: false});
if (navigator.userAgent.match(/msie/i)){
$.get("../get_email.php", function(data){
$("#IncidentCustomerEmail").val(data.email);
console.log("Got user's email Adress => " + data.email);
}, "json");
} else{
$("#emailDescription").text('No IE, please fill your email manually');
console.log('no IE')
}
});
</script>

Любой совет, который помогает отследить причину, высоко ценится.
Заранее спасибо!
