Many problems whith Post method

[Jose Luis Rodriguez]

I have many problems with method Post when I use Tomcat 3.2.1 + Nt 4.0 +
IIS + IE 5.x. When I use Netscape Communicator that's OK.

For example:
Page HTML:
 <form name="frm" action="proc_inicio.jsp" method="post">
  <P>Login: <input type="text" name="login" size="15" maxlength="10"
value="">
  <P>Password: <input type="password" name="password1" size="15"
maxlength="10" value="">
  <P><input type="submit" value="GO">
 </form>
Page Jsp:
    <%
     String login = request.getParameter("login");
    %>
    LOGIN = <%=login%>

Result:
1) Method Post:
    LOGIN = null        Bad
2) Method Get:
    LOGIN = mylogin    OK

What's happens?

Many thanks,
José Luis
