Speculative revalidation requests do not have their HTTP user-agent set.
We can probably save the original request's user-agent header in the cache and then re-use that one for speculative validation. We may also need to make sure the user-agent header used by the speculative validation matches the effective user-agent of the actual request from WebCore.
