I have added this in top of the aspx file:

  <META HTTP-EQUIV="Expires" CONTENT="Fri, Jun 12 1981 08:20:00 GMT">
 <META HTTP-EQUIV="Pragma" CONTENT="no-cache">
 <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">

It is now saving more offen but not all the time, why is this a problem to me (I am using Internet Explore 6.0 as default)?

What can i do to make tis work everytime?
