When a session times out, the system returns a page

The problem is persistant cacheing with some browsers (IE) which in
essence leaves many users stranded on that page.

This hack adds a unique number to the link, which inturn creates a new
URL. The script will ignore the number when it loads.

file:
Views/eXtropia/StandardTemplates/SessionTimeoutViews
/eXtropia/StandardTemplates/SessionTimeoutView.pm

my ($sec,$min,$hour,$mday,$mon,$year,$wday) =
   (localtime(time))[0,1,2,3,4,5,6];

$content .= qq[
<table width="100%" height="100%">
<tr>
<td align="center" valign="middle">

Yes, I know, if the number was reordered it would display the time, but
then it would NOT look like a unique number to the user :-)

changed all my header() calls to

(see CGI.pm for syntax)

XX is the time in minutes I choose as timeout minus a safety margin
(actually, it should be possible to get this time as variable from the script
for use in any View)

This takes care of the problem you specified.
