Use Case: Post Multipart Form Data With Custom Part Headers
I want to POST multipart form data, but I have to add custom headers to some of the parts. This option is mentioned by RFC 2068 in section 19.4.5.
The current 3.0 API allows only to set some standard headers for the parts (like StringPart , FilePart ,...), but not to add generic headers by name and value.
This use case was posted to the developer mailing list by Edwin Kempin on Valentine's Day (Feb. 14) 2005.
