Method for providing digital contents in a network environment in an embodiment includes the following. In a server, the digital content request is checked for its priority. Whether a queue is full is checked. If the queue is not full, the digital content request is added to the queue. If the digital content request is not of a high priority and the queue is full, a communication link to a client device corresponding to the digital content request is disconnected. If the digital content request is of the high priority and the queue is full, the digital content request is added to an additional queue appended to the queue. With respect to a first request, a digital content required by the first request is provided to a client device corresponding to the first request. The providing step is repeated for another request obtained from the queue.
