title: Spring java code form post and redirection to a different server
body: <p>I am building a web application using Spring framework that requires users to make a payment. When the user posts a form, it redirects to Hp's payment website and processes the payments there before returning to my application. This method however leaves my applications vulnerable to security threats and form manipulations. </p>
  
  <p>I now want to post the form to my server, validate users inputs and if necessary post data to hp's web server. I have already written a java code for posting a form from my code and getting the response back into a file from hp's site but am unable to figure out how to redirect the user to the hp website using the java form post. Can someone please help? I am new to Spring so am open to suggestions that would help me accomplish this task either using this method or another way to do so.</p>
  
  <p>Thanks</p>
