Comentários

Devido a comportamentos específicos do servidor e do recurso, como redirecionamento, o valor retornado pela RequestUri propriedade nem sempre é o mesmo que o valor retornado pela ResponseUri propriedade .

Para solicitações que usam o UploadFileWithUniqueName método , ResponseUri retorna o nome do arquivo no servidor.
