2.1.3.4.2.3 Content-ID, Content-Location, Content-Base

  • Article

MIME writers SHOULD generate a Content-ID header if the value of the PidTagAttachContentId property ([MS-OXCMSG] section 2.2.2.29) contains nonwhitespace characters. All trailing and leading whitespace characters SHOULD be removed from this value. If the resulting value does not start with "<" (U+003C), or does not end with ">" (U+003E), it SHOULD be enclosed in angle brackets. The resulting string becomes the value of the Content-ID header.

MIME writers SHOULD generate a Content-Location header if the PidTagAttachContentLocation property ([MS-OXCMSG] section 2.2.2.29) contains a value that is a valid URI. This value SHOULD be copied to the value of the Content-Location header.

MIME writers SHOULD generate a Content-Base header if the PidTagAttachContentBase property ([MS-OXCMSG] section 2.2.2.29) contains a value that is a valid absolute URI. This value SHOULD be copied to the value of the Content-Base header.
