Question

I am need to know what is Response.Clear and Response.ClearContent in Spring MVC.

Answer 1

Response.Clear() calls Response.ClearContent() (just a more matching name for the same function). There is no difference. Both clear the response stream except header infos.

public void Clear ()
{
  ClearContent ();
}

public void ClearContent ()
{
  output_stream.Clear ();
  content_length = -1;
}
