title: application returns 404 error after payumoney successful payment
body: <p>After payment is done. When payumoney redirects to my application with POST request. I am getting 404 even having request mapping.</p>
  
  <p>URL: [test.payumoney.com/payment/postBackParam.do:23][1] </p>
  
  <p>I tried with the plain form from my application, it is hitting my application. When it comes to request from another site, it is throwing 404 error.</p>
  
  <p>Do I need to change any server setting Where it should accept this kind of request?</p>
