> URL: https://issues.apache.org/jira/browse/SLING-1841
> Project: Sling
> Issue Type: Improvement
> Components: Authentication
> Affects Versions: Auth Core 1.0.2
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Fix For: Auth Core 1.0.4
>
>
> 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.
