AW: The never ending story: Turning caching off --- Oooops

Sorry, I just figured out, that the time stamp stuff works.
But I figured out another problem, that made me blind for understanding the cache problem.
I'll post it soon.

  Betreff: The never ending story: Turning caching off


  Hi everybody,
  I was looking for a solution for the all time favorite "Caching Problem" (in IE).
  I found a couple of "solutions, like:

  1) Having the following lines in the JSP:
  response.setHeader("Pragma", "NoCache");
  response.setHeader("Cache-Control", "no-cache");
  response.setDateHeader("Expires", 1);


  2) Turning "nocache" on for the ActionServlet:
  <init-param>
    <param-name>nocache</param-name>
    <param-value>true</param-value>
  </init-param>


  3) Adding an unique parameter to the get/post, like System.currentTimeMillis()

  See http://www.mail-archive.com/struts-user@jakarta.apache.org/msg03176.html
  to that idea.

  One answer was, that usnig tokens  is the key:
  http://www.mail-archive.com/struts-user@jakarta.apache.org/msg02888.html
  But, correct me, if I'm wrong, what's the deal with tokens,
  when I don't want a JSP to be cached?


  I tried all of them, but with no success. So, my question is: did I miss
  something or is it really just not possible?

  Thanks in advance,
  Holger
