We have a requirement to upload some files into the server during the process of a wizard. However, if the file upload fails at current step, the user is allowed to proceed to the next steps and restart file uploading at any stage of the wizard, without having to re-pick the files.
I understand it is of security reason that fileapi has disabled getting the address of the file and using the file address to initialize the file object. However, is it possible to use json to serialize that file object and store in Cookie/Session/Database and deserialize in the next pages?
If that's possible, will that also be a security issue? If not, is it possible to implement my scenario? Thanks a lot!
