Answer 1

I believe that the problem may be that your start and end boundaries are not on a new line according to this website. I would try putting CRLF's in prior to your boundaries.

The boundary delimiter MUST occur at the beginning of a line, i.e., following a CRLF, and the initial CRLF is considered to be attached to the boundary delimiter line rather than part of the preceding part. The boundary may be followed by zero or more characters of linear whitespace. It is then terminated by either another CRLF and the header fields for the next part, or by two CRLFs, in which case there are no header fields for the next part. If no Content-Type field is present it is assumed to be "message/rfc822" in a "multipart/digest" and "text/plain" otherwise.

(This was edited because I was initially mistaken, I thought that every boundary had to be closed)
