Spring-MVC controller redirect to “previous” page?

Question

Let\'s say I\'ve got a form for editing the properties of a Pony, and in my web application there are multiple places where you can choose to edit a Pony. For instance, in a li

My answer is alike to Sam Brodkins´s (i recomended it also). But having in count that the "Referer" value may not be available i made this function to use it in my controllers

/**
* Returns the viewName to return for coming back to the sender url
*
* @param request Instance of {@link HttpServletRequest} or use an injected instance
* @return Optional with the view name. Recomended to use an alternativa url with
* {@link Optional#orElse(java.lang.Object)}
*/
protected Optional getPreviousPageByRequest(HttpServletRequest request)
{
   return Optional.ofNullable(request.getHeader("Referer")).map(requestUrl -> "redirect:" + requestUrl);
}

So in your controller caller function you should return something like this:

@RequestMapping(value = "/upload", method = RequestMethod.POST)
public @ResponseBody
String testRedirection(HttpServletRequest request)
{
      //Logic....
      //Returns to the sender url
      return getPreviousPageByRequest(request).orElse("/"); //else go to home page
}
