* target="_blank">HTML/JS response</a> for the File Browser <code>POST</code>
* requests.
* <p>
* This class utilizes varags to reflect the JavaScript callback function in an
* optimal way. However, varargs can be tricky. You can always omit passed
* parameters from right to left but any violation may result in an exception or
* a failed callback.
* </p>
* <p>
* For example: <code>window.parent.OnUploadCompleted(101,'some/url/file.img','file.img','no error')</code> can be mapped with
*
* <code>UploadResponse ur = new UploadResponse(SC_SOME_ERROR,"/some/url/file.img","file.img","no error")</code>
* .
* </p>
* <p>
* But <code>window.parent.OnUploadCompleted(101,'some/url/file.img','no error')</code> is an illegal callback and
* will fail.
