title: Send HTTP POST request in Spring MVC
body: <p>I am working on a project that uses Spring MVC, and one of the requirement involves sending request to an external services to handle some transactions.
  The problem now is the external services only takes POST method, and I've looked everywhere and could not find a way to forward user to external site as a POST request(similar to form submit).</p>
  
  <p>What we are trying to do:</p>
  
  <p>1) My Controller will receives request and execute some backend thing and construct some parameters to pass on.</p>
  
  <p>2) *Send request to external service via HTTP POST method with some parameters.
  (note. User's browser will show URL of the external site.)</p>
  
  <p>I've looked into different return types for Spring MVC and could not find anything that fits.</p>
  
  <p>Any advice would be greatly appreciated.</p>
  
  <p>Thanks!</p>
