Method for the provision of locally stored content data for a mobile terminal of a user through an access point, comprising the following steps: (a) receiving a browser request sent by the mobile terminal via a wireless interface to the access point, wherein the browser request contains a URL address for access to a web server; (b) replacing the URL address of the web server contained in the browser request by a preconfigured URL address through a proxy server implemented at the access point, wherein the preconfigured URL address indicates a storage location of content data stored locally in a data store of the access point; wherein the URL address contained in the browser request is buffered in a buffer; (c) reading out the content data addressed through the replaced preconfigured URL address from the data store of the access point; wherein the method is characterised by the following steps: (d) back-replacing the preconfigured URL address in all the read-out content data by the URL address originally contained in the browser request of the mobile terminal, which URL address is read out from the buffer, wherein the back-replacement is effected through the proxy server implemented at the access point; and (e) transmitting the content data read out from the data store of the access point from the access point to the mobile terminal of the user as a reply to the browser request received from the mobile terminal through the access point, wherein a notification that the content data contained in the reply originate from a URL address replaced through the access point and not from the URL address originally contained in the browser request is transmitted to the mobile terminal of the user upon reply to the browser request of the mobile terminal in such a way that this notification is presented by the browser of the mobile terminal in a manner visible to the user, wherein the reply contains the URL addresses back-replaced by the proxy server.
