How do I access the headers I set in middleware?

[WillPwn4Food]

So with middleware I can set custom headers by doing something like: response.headers.set('x-utm-date', utmDate);, that seems easy enough, similar to how I set the cookies, which works.

Now when I load my static page, I'd love to see those custom headers I just sent over so I can take action on them, but I have no idea how to access them or if it's even possible. I can't find any documentation on this. I assume I would have to do it in useEffect or is it somehow passed in as a prop that I don't know about?

Please let me know if you have any ideas. If I can't access it, what's the point of setting the headers?
Thanks,

Not positive, but it sounds like the issue is that you're trying to use getStaticProps instead of getServerSideProps. The former is going to be called at build time and serve static HTML/JS. It shouldn't be used in situations where you need to read some variable set at runtime on every request.
