    Parameters

    name

    The header field name whose first value should be retrieved.

    Returns

    The first value for the header field name.

    This method uses case-insensitive comparisons for the header field name. It does not return the first value from a maximally-decomposed list of the header fields, but instead returns the first value from the original representation: that means that a comma-separated header field list may contain more than one entry, some of which contain commas and some do not. If you want a representation of the header fields suitable for performing computation on, consider subscript(canonicalForm:).
