I am creating a page where students log in their attendance for a class by putting in their SID and a key provided by the professor. Then it will go through the servlet and post that the student was there on a google spreadsheet (backend). My question is, after the SID is confirmed and everything how can i redirect them to a "Thank you for your Submission" page? We want them to get a confirmation page, so that they can have a receipt to show the professor that they were in class. We would like to later implement it where we can even send a email confirmation page to the student.
<body>
<div id="title">
<h2>CSC 131 Student Attendance</h2>
</div>
<div id="login">
<form action ="QuickServlet" method="post">
<h2>Student:</h2>
<center><input type="text" id="key" placeholder="Enter Key:"/></center>
<center><input type="text" id="Studentid" placeholder="Enter StudentID:"/></center>
<center><input type="submit" id="mySubmit" value="Submit"/></center>
</form>
</div>
