A method for an intermediary node to reduce a number of server-client sessions between a server (104) and a plurality of clients (102a, 102b, 102c) communicably connected to the server (104) over a network is disclosed. The intermediary node (106) intercepts a first request and a second request destined to the server (104) from a first client (102a; 102b; 102c) and a second client (102a; 102b; 102c). The intermediary node (106) establishes a server-client session, between the intermediary node (106) and the server (104), using the first request. If the first request overlaps in part with the second request and if a part of the second request is not overlapping with the first request, the intermediary node (106) updates the server-client session between the intermediary node (106) and the server (104) to include a part of the second request.
