Transaction happens twice.

Question

Transaction happens twice.
I need two files to demonstrate this
File 1.) index.jsp
<?xml version="1.0" standalone="no"?>
<%@ page contentType="image/svg-xml" %>
<svg >
<text x="200" y="100" stroke="navy" >GPro</text>
</svg>
File 2.)
public class Account extends HttpServlet {
protected void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException,IOException {
     System.out.println("Login5");
RequestDispatcher disp=req.getRequestDispatcher("/pages/index.jsp");
     disp.forward(req,res);
The servlet doesn�t do anything but always forwards the request to an SVG document.
The problem,
When I call this method width the following URL:
http://servername/Account?a=1
http://servername/Account?a=2
http://servername/Account?a=3
You always have to have different URL to see this result in the log file:
[02.04.16 10:22:33:500 MDT] 3d74e6fe SystemOut U Login5
[02.04.16 10:22:33:609 MDT] 3d74e6fe SystemOut U Login5
[02.04.16 10:22:53:875 MDT] 3d74e6fe SystemOut U Login5
[02.04.16 10:22:53:953 MDT] 3d74e6fe SystemOut U Login5
[02.04.16 10:23:10:375 MDT] 3d74e6fe SystemOut U Login5
[02.04.16 10:23:10:500 MDT] 3d74e6fe SystemOut U Login5
The servlet executed twice .
This happens always when I use IE 5.5 sp2 and Adobe SVG Viewer 3.0
It is working well with Netscape 4.08
I have the following in the log file
[02.04.16 11:05:15:187 MDT] 3d74e6fe SystemOut U Login5
[02.04.16 11:05:24:796 MDT] 3d74e6fe SystemOut U Login5
[02.04.16 11:05:38:312 MDT] 3d74e6fe SystemOut U Login5
[02.04.16 11:05:44:328 MDT] 3d74e6fe SystemOut U Login5
You may see it never happens twice.
I�d like to know what your opinion about this.
Thank you,

Thanks,
Unfortunately, the bug is somewhere else.
I just used a very simple test program no javascript nothing and I just typed those URL�s in the address bar.
Last time I tried this: ( this is the doGet method of my test servlet and nothing more );
PrintWriter out=res.getWriter();
String s="<?xml version='1.0' standalone='yes'?>"
+"<svg >"
     +"<text x='200' y='100' stroke='navy' >GPro</text>"
     +"</svg>";
out.print(s);
out.flush(); out.close();
There is nothing special here and the servlet got executed twice if I used explorer.
It seems to me the SVG viewer for some reason tries to revalidate the document .
