I have a JSP page with frames, and when I resize the browser window or if I
resize a frame, I get:

Data Missing

This document resulted from a POST operation and has expired from the cache. If
you wish you can repost the form data
to recreate the document by pressing the reload button.

In my JSP pages, I have the following to prevent caching:

response.setHeader("Pragma","No-Cache");
response.setDateHeader("Expires",0);
response.setHeader("Cache-Control","no-Cache");

Is this a frame problem?  Is this a general problem with dynamically-generated
pages?  Is this happening because of the code
to prevent caching?

Is there any way around this problem?

Thanks,
Patty
