 * it has memory leak when send multipart/formdata
 * it does not save string for curl options that may result crush in libcurl
 * there no way to get result for operations in multi interface (e.g. if one of easy operation fail you can not get result code/error message)
-* you can not use multi interface for upload operation (?)
 * you can not use your own callback function to perform operation with multi interface
 * you can not pass your context to callback functions
