What should a Multipart HTTP request with multiple files look like?

Question

I'm working on an iPhone app that makes a multipart HTTP request with multiple image files.

It looks like what's happening, on the server side, is that one of the images is getting parsed properly, but the other two files are not.

Can anybody post a sample HTTP multipart request that contains multiple image files?

Answer 1

Well, note that the request contains binary data, so I'm not posting the request as such - instead, I've converted every non-printable-ascii character into a dot (".").

Note that every line (including the last one that ends with "322--") is terminated by a \r\n sequence.
