SSL cache issue

[Terry Ziemniak]

I am getting 'page not found errors' the first time I access certain JSP pages (though there are others that always work).  If I refresh the page displays correctly.    Notes: This only happens over HTTPS, never over HTTP Netscape (v 4.2) displayed the error "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 create the document by pressing the reload button." Apache's access.log seems to validate point 2.  The last line before an error is a POST.  The retry shows a POST followed shortly by anther GET and POST of the same JSP. I have not yet been able to exactly describe 'First time'.  General rule of them, if I repeat the process within 15 minutes it seems OK.  If I wait an hour it should fail.  Though quantifying that has not been my highest priority. I am running Apache_1.3.20-Mod_SSL_2.8.4-OpenSSL_0.9.6a-WIN32 and Resin 1.2.8.   Any help would be appreciated.   Terry Ziemniak
