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

[Byron Campen]

	Doing this would be tricky. It would probably involve leaning on  
HeaderHash::in_word_set() (this will map a string to a header-type)  
and a very large switch statement on the header-type. This would be  
time-consuming to say the least, and prone to breakage if new header- 
types are added.

Best regards,
Byron Campen
