Helo Amos!
Thanks for answering that soon!

I'm afraid it's not the beloved X-Forwarded-For header. This CDN sets a
few headers by their own, and their are completely custom.

What I was looking for was a way to analyze the HTTP Headers coming from
them and perform certain types of operations, like comparing them
against a blacklist, add them into buckets, or stuff like that.

Unfortunately I was not able to find the way to do it using
url_rewrite_program, in case it does support it.
