Hey Boris,
Good catch! To count as a security measure, we would need to do this for any anchor (through WAnchor or a in XHTML content) when the current page has the wtd in the URL (e.g. in plain HTML sessions or when reload-is-new-session is false).
Apparently, do a server-side redirect will replace the Referer correctly, so we would need to replace:
with and implement in WebSession a special 'redirect' request

Hey,
We've implemented just this: to use a redirect-indirection in case the current URL contains the (current) session Id.
We still should add this to a few other places, like in the XSS filter and for image src URLs.
