HTTP headers

[Ray Lischner <ray.lischner@uscontractinginc.com>]

Section 6.12.2 HTTP Request Extension states that the request_header 
property has type dictionary, and type dictionary (section 2.3) requires 
keys to be from the restricted character set of ASCII alphanumeric, 
hyphen, or underscore. This poses a problem for HTTP headers that have 
names outside of this character set. Although the standard headers 
conform to the restricted character set, custom headers may not. 
Preserving original the header names of malware traffics is critical for 
reporting and detecting the malware. (For one example, see 
https://community.rsa.com/t5/netwitness-discussions/plugx-apt-malware/td-p/460307, 
and the header name "ASH-1.0".)

What is the recommended practice for preserving the header names while 
conforming to the standard?
