2.2.3.2.29 Generic Headers in PS_INTERNET_HEADERS
To create a named property in the PS_INTERNET_HEADERS property set, whose name is a header name and whose value is a header value, clients write the name and value to a header.
For each such header, MIME readers SHOULD<141> create a named property as follows:
The property set GUID is "%X86.03.02.00.00.00.00.00.00.C0.00.00.00.00.00.46".
The property name is the header name.
The property value is the header value. If the header value was encoded according to [RFC2047], MIME readers MUST decode it.
MIME readers MUST NOT create such named properties for any MIME header that is mapped to a different property, as specified elsewhere in this section. MIME readers SHOULD NOT create such named properties for any of the following MIME headers:
