HttpServerResponse: single HTTP header with multiple values

[Chris Bailey]

I see that the HttpServerResponse has an interface to specify multiple header values in a single call e.g., putHeader(String name, Iterable<String> values) and from some initial testing it looks to add multiples instance of the header, each with one value.

For compatibility reasons, we need a single header with multiple values separated by a delimiter.  Is there a way to specify this behavior or do we have to construct the single value per our requirements?

Thanks,

Chris
