Whether to merge or add

http://apr.apache.org/docs/apr/1.3/group__apr__tables.html

depends on whether you need the various (header) values to get 
concatenated with ", " in between and the header send only once, or you 
want the headers multiple times, each time with a different value.

What's right depends on the spec that defines the header. Set-Cookie 
requires the header once for each cookie to set.
