This looks good. I do have three observations:
1.) One of the things that doesn't seem clear is the 'everything is
append by comma rule'. I think the intention is that the rule only
applies to the headers that aren't covered in the exceptions section,
but I can't be sure from the wording.
For example, if User-Agent: is allowed to be appended to, shouldn't
that be an exception to the 'everything is appended with a comma'
rule, given the formatting rules for the User-Agent header require it
to be space separated. Same idea for Cookie headers using ';' as a
2.) Does the fourth bullet, with it's restriction on the
If-Modified-Since, If-None-Match, If-Range, and Range headers, only
apply if the method is 'GET" or 'HEAD'? I would hope they could be
overridden if the method were PUT, POST, DELETE, etc.
3.) What is the reasoning for restricting the Range header even in the
case of a GET/HEAD? I am in particular thinking of cases where the
units of Range are not 'bytes' but some custom value.
