Claus Ibsen commented on CAMEL-1886:
------------------------------------

Hadrian I have now a solution using the KeyValuePair object as holder.

It works as well with the scripting engines when I go the extra mile and 
_washes the KeyValuePair object away_ when they get hold on the headers.

The other solution that does *not* use KeyValuePair do not need to do this and 
thus is more elegant. However it requires to keep booking of the lower case 
keys -> original key in a 2nd internal map.

So in result we got 2 possible solutions
a) Use KeyValuePair holder objects (that holds original key and value)
b) Use internal 2nd map to keep booking of lower case key -> original key

I will attach new files with a and b code

> Today the case matter so: getHeader("Foo") and getHeader("foo") is not the 
> same.
> And for some protocols the header case do not matter such as
> - http
> - mail
> etc.
> And who would in real life want to send 2 headers that are different only 
> depending on the case
> - Foo=me
> - foo=you
