For compatibility with header splitting, the delimiter should be a comma, The following header:

    I'm-Not-A: freezer, teapot, radio
is equivalent to:

    I'm-Not-A: freezer
    I'm-Not-A: teapot
    I'm-Not-A: radio
even in cases where the client, server, or some intermediate proxy doesn't know the I'm-Not-A header.
