>Description:
Under IE 4.0, everything works fine and redirection is quick. However, under
Netscape 4.61, it takes about 4-6 seconds before the redirected page is
displayed.
If I use another Servlet engine (e.g. JRun), this problem doesn't occur.
>How-To-Repeat:
TestServlet.java:
---------------------
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class TestServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
out.println("<HTML><HEAD>");
out.println("<TITLE>HTML directory");
out.println("</TITLE></HEAD><BODY TEXT=\"#800000\"
BGCOLOR=\"#FEFBEB\"><FORM METHOD=\"POST\" >");
out.println("<BR><INPUT TYPE=\"SUBMIT\" VALUE=\"Test redirect\"
NAME=\"Test redirect\">");
out.println("</FORM></BODY></HTML>");
out.close();
}
public void doPost(final HttpServletRequest req,
HttpServletResponse resp)
throws ServletException, IOException {
int port = req.getServerPort();
String abs = req.getScheme() + "://" + req.getServerName() +
(port == 80 ? "" : ":"+port) + "/servlet/HelloServlet";
System.err.println( "Redirecting to: " + abs + " resp class name:" +
resp.getClass().getName());
resp.sendRedirect( abs );
}
}
----------------
HelloServlet.java
-------------------
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
out.println("<HTML><HEAD>");
out.println("<TITLE>Hi there");
out.println("</TITLE></HEAD><BODY TEXT=\"#800000\"
BGCOLOR=\"#FEFBEB\"><FORM METHOD=\"POST\" >");
out.println("Hi there </FORM></BODY></HTML>");
out.close();
}
}
Call TestServlet and press "Test redirect" under Netscape 4.61 (try this
with IE 4.0 and see the speed difference).
