The invention discloses a method for accessing and viewing Internet content on a portable device by means of a proxy server, which method reduces the amount of data transferred to the device and improves its performance. Based on the content of each part of a web page, the server calculates, assigns and saves unique identifiers for each of them. If the web page is revisited or refreshed, unique identifiers are calculated and assigned for parts of this revisited or refreshed page. Parts that have the same identifier as a part previously saved are not transferred as the part with the same identifier in a memory of the device is instead used for display. Various processes can be combined with this method to reduce the number of instances by which the display of the device is refreshed and to optimally adapt the settings of the server's browser.
