I'm very far from being any kind of expert on the subject, but I have 
been doing a little research into HTTP headers so FWIW x-headers seem 
to be mostly associated with email.
There's no mention of them made in

The Pragma field, specifically the extension-pragma definition, which 
allows "key=value" fields, seems to me to be the best bet.

It would be great though, to have someone who really knows the topic 
weigh in.
