For session tracking to work, look at the following 2 methods
resonse.encodeURL
and
response.encodeRedirectURL
In this way, session tracking will only work when following links because
URL re-writting requires a link to modify whereas cookies go by the domain
within the HTTP request.
So, to make your example work you would have to add
<a href="<%=response.encodeURL(address)%>">Click me</a>
