java - How to redirect from inside a JSP

Question

I have a JSP page and need to introduce conditional redirect logic. For instance, if a variable is above a certain threshold, then continue rendering the JSP like normal. Otherwise, I need to redirect the browser to, say, http://myapp.example.com/fizz.

if(var > threshold) {
    // Render page like normal
} else {
    // Redirect to http://myapp.example.com/fizz.
}

Any ideas as to how I could accomplish the redirect portion of this (from inside a JSP page)?

Answer 1

Use

 reponse.sendRedirect("http://myapp.example.com/fizz");

Just add this
