[reSIProcate] Does there have a common way to got RFC headers value and extension headers value ?

[Karlsson]

Thank you Byron, I have checked the HeaderHash class, but I do not know how
to use for me.
And do not found any example on the reSIProcate source code and with and
mailist.

Can you please give me tips?

thanks
