Maybe when you tell what you're trying to achieve, we can give you
better advice.

Almost no one is looking for random strings in random headers, since
headers are (somewhat) structured data. Could you share with us what
string you are looking and why you don't know up front which header
field you need to use to look for it?

Kind regards,
