Faces 3 + Soteria: redirect on viewexpired on ajax request

Actually Soteria do not manage this, which is the best place to implement the correct "ajax" redirect?

something like the one proposed by BalusC

[https://stackoverflow.com/questions/13366936/jsf-filter-not-redirecting-after-initial-redirect/13369719#13369719](https://stackoverflow.com/questions/13366936/jsf-filter-not-redirecting-after-initial-redirect/13369719#13369719)

```
String loginURL = req.getContextPath() + "/login/login.xhtml";

if (!authenticated && !req.getRequestURI().equals(loginURL)) {
if ("partial/ajax".equals(request.getHeader("Faces-Request"))) {
res.setContentType("text/xml");
res.getWriter()
.append("")
.printf("", loginURL);
} else {
res.sendRedirect(loginURL);
}
} else {
chain.doFilter(request, response);
}
```

No file, test, or entry point is named. Start by tracing how Soteria handles expired views and authentication redirects, then investigate how Faces-Request marks AJAX requests. Done means the correct redirect behavior is defined and verified for both AJAX and non-AJAX requests.
