[http] HttpCore: staticfile() to process internel (error-)redirects properly

We did not honor the prior response status code yet and even interpreted
the usual staticfile() relevant request headers, which we shouldn't.

To prevent accidental evaluation of real-request request-headers and
alike, we could also introduce virtual requests... I'll need to rethink
about it, though.
