Http headers

[Guilhem Lavaux]

Hi,

If you try the mauve test URLConnection/Http you may notice there is
failure due to an unknown header "server" which should be "Server".
Apparently to make the search throught header fields independent from
the case we have using toLowerCase for all header keys and values: this
is not right. I suggest we build keep the original value in the array in
HeaderFieldHelper so we are able to return the exact value returned by
the server.

Comments ?

Cheers,

Guilhem.
