I have a small question, does the MIME headers have to be case sensitive ?
for example Content-Type in the RFC 2045 (https://www.ietf.org/rfc/rfc2045.txt) its enclosed in double quotes.so does content type header in the multipart request body has to be case sensitive ?
5.1. Syntax of the Content-Type Header Field
In the Augmented BNF notation of RFC 822, a Content-Type header field value is defined as follows:
content := "Content-Type" ":" type "/" subtype
*(";" parameter)
; Matching of media type and subtype
; is ALWAYS case-insensitive.
