I have two jsp files. The first jsp accept user input in form and then it calls the second jsp using Form action. And in the second JSP, it passes those two inputs to my Java Bean program, and then accept the output again from java bean and show the result using jstl.

So I input some data in the first html and then after hit the button, then it shows the result in the second page.

What I want to ask is: when I click on the 'back' button of the browser, the value I put in those text boxes are still there, what I want to do is every time I open that page, clear the text boxes and the curso will be in the first text box. How can I do this?

Thanks!!

Here's my two jsp files:
Search-input.jsp
 
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <link href="wixIndex.css" rel="stylesheet" type="text/css">
        <title>Web Index</title>
    </head>
    <body>
 
		<%@ include file="header.html" %>
 
        <form name="Name Input Form" action="search-result.jsp">
        	<br> &nbsp;
            <font color="0066CC" size="2"><b>KEYWORD</b></font>  
            &nbsp; &nbsp;
            <input type="text" name="keyword" size="80"/>
            <br><br> &nbsp;
            <font color="0066CC" size="2"><b>CONTENT</b></font>  
            &nbsp; &nbsp;
            <input type="text" name="kwinfo" size="80"/>
            <br><br>
 
            <input type="submit" value="SEARCH" class="button"/>
            <br><br>
 
        </form>
 
    </body>
</html>
