A servlet request is read-only.  To make the HTTPS -> HTTP transition 
will require a redirect.
e.g.

public void loginSubmit(IRequestCycle cycle)
{
    // login logic
    RequestContext request = cycle.getRequestContext();
    ILink link = 
cycle.getEngine().getService(Tapestry.PAGE_SERVICE).getLink(cycle, 
cycle.getPage(), new String[] { "Home" });
    throw new RedirectException(link.getAbsoluteURL("http", 
request.getServerName(), 80, null, true));
}

In my own applications I use a custom RedirectException implementation 
(I posted it a while back) that aims to encapsulate this type of url 
generation logic.
