SharePoint 2010 - Updates are currently disallowed on GET requests

Sometimes, when we create a new web application in 2010 and click on 'General Settings' or 'Resource Throttling' menu of it, we used to get the following error.

It occurs randomly for few web applications and the error disappears automatically if try using these menus after few days of creating the web application. Not sure about the reason, but found a workaround/solution from here.

The solution is to ensure the settings in powershell:

           $w = get-spwebapplication http://nameofwebapp/

           $w.HttpThrottleSettings

           $w.Update()

It worked well and we are able to get the settings page now without any issues.
