Go to the jsp page by clicking the back button

I have one 2 jsp pages and one Servlet. I retrieve the data from the database with the servlet and send the result to the page result.jspwhere I show the result. But I want to add Back buttonin result.jsp, by clicking Back button, I want to go to index.jsp, but the problem is that when I press the back button every time a message arrives Confirm form submissionand it annoys me, How can I avoid this Confirm form submission? perhaps this will happen because the processing is done in the servlet.

index.jsp

<form method="post" action="Student">

<input type="text" name="studentname"/>
<input type="submit" value="search"/>

</form>

Student servlet

 String student_name=request.getParameter("studentname");

  -------fetching data from database------------
  -------------------sending to result.jsp------

  String nextJSP = "/result.jsp";
      RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(nextJSP);
      dispatcher.forward(request,response);

result.jsp

 //displaying data here

<form action="index.jsp">

 <input type="submit" value="back"/>// a back button is here which is going to index.jsp   
</form>

EDIT

From result.jspI go to another page result1.jspas shown below

In result.jspI wrote the following:

<a  href="result1.jsp.jsp?a code=<%out.println(student_name);%>"><%out.println(student_name);%></a>

By clicking the hyperlink above, I went to result1.jsp

( result1.jsp), " result.jsp", "" Confirm form submission . result1.jsp

<input type="button" value="Back" onclick="javascript:history.go(-1)">

Working around represents your form using the get method. Of course, this is true only for "small" forms (max. 2048 K).
