That does look like a potential issue.  However, I think I may have
tracked this down to cookies and switching between HTTP and HTTPS.

There are two scenarios:
1) User starts at an HTTP page and is given a cookie.  This cookie can
be used in secure
and non secure requests.

2) User starts at an HTTPS page and is given a cookie.  This cookie is
only valid for secure requests (because it has Set-Cookie: ....
;Secure in the response header).  When a user is redirected to an HTTP
page they are given a *new* cookie and a new HttpSession is created on
the server.

Can you tell me the exact semantics of the secure attribute on the
<connector> element?  The documentation just says "Set this attribute
to true if you wish to have calls to request.isSecure() to return true
 for requests received"

Thanks
