A proxy server (102) for downloading a data file for a client (108), such as an email client or web browser, includes: an external proxy (204) for downloading the data file for the client (108) from an external server (104) over a network (106), based on the profile data associated with the client (108) stored on the proxy server (102); a memory module for storing the data file; and an internal proxy (208) for transferring the data file to the client (108) when requested by the client (108). The external proxy (204) operates asynchronously with the internal proxy (208), and the proxy server (102) operate transparently with respect to the client (108). |
