Usage

First obtain the raw data of the request in the framework you are using:

byte[] data = ... posted data

String contentType = ... header "Content-Type"

Then call customized FileUpload to process the request:

FileItemIterator iterator = FileUpload.parse(data, contentType);

Finally, process the items in the multipart request:

while (iter.hasNext()) {
    FileItemStream item = iter.next();

    if (item.isFormField()) {
        ... some fields in the form
    } else {
        InputStream stream = item.openStream();
        // work with uploaded file data by processing stream ...
    }
    
}
