Abstract: Disclosed is an electronic device includes a flexible display, a support structure that supports the flexible display and a housing, into which the flexible display and the support structure are inserted. When the support structure is inserted into the housing, the flexible display is inserted into the housing together with the support structure while being wound in a specific direction. When the support structure extends outside the housing, the flexible display is deployed so that the flexible display is substantially flat.

Abstract: The present invention relates to a proxy apparatus and to a caching method of same. The caching method of the proxy apparatus according to one embodiment of the present invention includes the steps of: receiving a transmission request for content that can be divided into a plurality of blocks and instruction information for the playback position of the content from an external device; obtaining a header block that includes the header of the content when receiving the transmission request; identifying an intermediate block that corresponds to the playback position using the header; requesting and obtaining the intermediate block through a network when the identified intermediate block is not cached in the proxy apparatus; and transmitting to the external device at least a portion of the header and at least a portion of the intermediate block corresponding to the request. According to one embodiment of the present invention, even in a case where the size of a piece of content is great but only a specific portion is used, an efficient caching method and apparatus can be provided.
