> The AbstractAuthenticationHandler.sendValid currently sends back a simple 200/OK response with no furtĥer content etc. This simplicistic response has two drawbacks:
>   * Firefox tries to XML parse the empty response and logs an error because this fails
>   * IE 8 seems to aggressively cache such validation requests if sent with an XHR GET request even though the request has parameters
> To prevent these situations the sendValid method should set cache control headers to prevent caching the response and set the content type to text/plain with an explicit zero content length to prevent firefox from trying to parse the result.
