Ko e hā ʻoku maʻu ai ʻe Squid ha UDP socket ʻi ha puha ʻikai fakafuofuaʻi
Fakangatangataʻi ʻa e ngaahi UDP socket DNS mo e peer-cache ʻa Squid mei he TCP listener ʻoku fakaʻaongaʻi ʻe he kau klieni ko ha proxy ʻi muʻa.
Ko ha puha UDP taʻeʻiloa ʻoku ʻi he pule ʻa Squid ʻoku ʻikai foki ia ko ha HTTP proxy ʻo e kakai kotoa. ʻOku fakaʻaongaʻi ʻe he kau klieni ʻa e TCP listener kuo fokotuʻu ki he hū ki he HTTP proxy; ʻoku fakaava foki ʻe Squid ʻa e ngaahi socket ki he DNS mo e fetuʻutaki mo e peer cache.
Koeʻuhi ke ʻiloʻi ʻa e socket ʻoku toe, hiki: pe ko e TCP pe UDP, ko hono tuʻasila kuo haʻi mo ha faʻahi mamaʻo ʻoku fakahā; ko e ngaahi fokotuʻu ʻoku ngāue ʻa e listener, DNS, ICP mo HTCP ki he ʻīnsitānisi ko iá; mo e aʻu ʻi he netiueka ʻoku fiemaʻu ʻe he meʻangāue ʻoku fakaava ʻe he ngaahi fokotuʻu ko iá.
