I'm implementing multi-part file upload with the following library: Commons FileUpload
Since the files may be too large, I don't load the entire file to the the memory, I just do the job on the bytes as fast as they arrive. The problem that I have met is that I need the full size of the file to continue my processing. As the easiest solution I think about asking Front-End to send Content-Length headers for each part of multi-part request.
However, during the implementation, I need to be able to test that as well, and the problem here is that using Postman, I don't think that it provides default features to setup additional headers to multi-part request parts.
For now I use: Body->form-data->key-type = file.
The question is there a way to specify additional headers in Postman for different parts of the request? Hardcoding this data in the code is not that dynamic even for testing.
