This post helped a lot connecting an iPhone to a Ruby server. One thing I did have to do differently was change:

“Content-Type: image/jpg
”

“Content-Type: image/jpeg
”

Thanks!

I think this is a bug with Ruby’s multi part parser. PERL will handle the leading ‘\r\n’ just fine and the RFC on the topic (2046) states:

‘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.’

e.g. it is correct to have that \r\n at the beginning of the boundary line.

….er, and it did it in my comment, too.

One problem I rant into, the browser is converting the double dash before the boundary into an mdash:
@”–%@\r\n” instead of
@”–%@\r\n”

Changing that got it working. Thanks!
