I have an SHtml.ajaxSelect that, when executed sets a cookie:

S.addCookie(HTTPCookie("CITYID", city.id.toString))

and then returns a JsCmds.RedirectTo(uri) command. The cookie isn't
actually being set (if I look at the live http headers the Set-Cookie
line isn't sent down in the http response to the ajax call).
