Combining Headers

Description (last modified by mnot@…)

In ​http://trac.tools.ietf.org/html/draft-ietf-httpbis-p1-messaging-21#section-3.2 one reads

"Multiple header fields with the same field name MUST NOT be sent in a message unless the entire field value for that header field is defined as a comma-separated list [i.e., #(values)]."

In practice, naive implementation can result in unintended results, e.g., 

  Location: http://abc.com
  Location: http://xyz.com

Some implementations will choose the 1st one, some will choose the 2nd one, and some may see the merged http://abc.com,http://xyz.com (a valid URI).

Conclusion on the list is that we don't need to address this further than what has already been covered for framing.
