I was wondering whether it\'s possible to upload a file from Mathematica to ifile.it. I have seen the API of ifile.it, however, I still don\'t know how it works. Furthermore

ragfield's answer gets points for not being a hack, but you can also do this without JLink:

UploadFile[url_, filePath_, urlParams___] := With[
  {
    bytes = Import[filePath, "Byte"],
    filename = StringJoin[FileBaseName[filePath], ".", FileExtension[filePath]]
  },
  URLExecute[
    url,
    urlParams,
    "Method" -> "POST",
    "MultipartElements" -> {
      {"file\"; filename=\"" <> filename, "application/octet-stream", bytes}
    },
    "Headers" -> {
      "Accept" -> "application/json; charset=UTF-8",
      "Content-Type" -> "multipart/form-data"
    }
  ]
]
