We have a Gears object that is not yet in the 'official' build that does
allow script to compose a multi-part/formdata payload. Not sure when this
will make its way into a real build.
interfaqce BlobBuilder {
void append(string|blob); // string data will be utf8 encoded in the
resulting blob
Blob getAsBlob();
};
With this interface you still have to manually compose the multipart
boundaries, but in the end, you can create a valid multipart payload
including binary file parts.
