Set default output headers when a rewrite response is returned
Set default output headers when a rewrite response is returned

Because a response can be returned by the module used to rewrite arg records,
we must take care to set default output headers like 'date' and 'server'.
When the response has a content, if the content type is not defined, then
we set it to "text/plain".
