I-CDN imele "iNethiwekhi yokuThuthukiswa kweNkcazo" kwaye yinkqubo yeekhompyutheni kunye neempendulo kunye nezinye iziqulatho zazo ezisetyenziswa kakhulu ngamaphepha amaninzi ewebhu.

Kodwa kukho okungakumbi. IiNethwekhi zokuThumela iiNkcukacha zenzelwe ukuba zigcinwe kumgangatho wenethiwekhi. Ngoko ke, nokuba ngaba umthengi akavakalisi kwenye indawo usebenzisa i-jQuery, amathuba ukuba umntu onobuhlobo bunye wenethiwekhi njengokuba sele uhambele isayithi usebenzisa i-jQuery. Kwaye ke le node ibambelele kuloo ndawo.

Ngethuba lokuqala iphepha liceliwe, ngabani na, lwakhiwe kwiseva yewebhu. Kodwa ke ikhutshwe kwi-server ye-CDN. Emva koko xa omnye umthengi efika kwiphepha elifanayo, okokuqala i-CDN ihlolwe ukuba iqinisekise ukuba i-cache ifikeleleki. Ukuba kunjalo, i-CDN iyakunikela, ngaphandle koko, iyayicela kwiseva kwakhona kunye neecaches ekopiweyo.
I-CDN yezorhwebo iyithuluzi eluncedo kakhulu kwiwebhusayithi enkulu efumana izigidi zeembono zekhasi, kodwa kungenzeka ukuba ingabi neendleko kwiiwebhsayithi ezincinci.
