'AllowUnsafeUpdates' property on Central Administration

Sometime we got the error on Central administration >> general settings like this:

Updates are currently disallowed on GET requests.  To allow updates on a GET, set the 'AllowUnsafeUpdates' property on SPWeb.

Solution-:run this command on Microsoft sharepoint 2010 products (sharepoint 2010 management shell)

$w = get-spwebapplication http://mossapp:1000 <<your url>>
$w.HttpThrottleSettings
$w.Update()
