Metodo GET : Isetyenziselwa ukucela idatha kumthombo othile
Metodo POST : Isetyenziselwa ukuthumela idatha kwiseva ukuhlaziya uvimba

Indlela `GET`

Indlela yeHTML yeGET isetyenziswa ukufumana uvimba kumncedisi.

Indlela ye-HTTP ye-GET yongeza umtya wombuzo ekupheleni kwe-URL ukuthumela idatha kumncedisi. Umtya wombuzo ukwimo yeperi key=value kwandulelwa uphawu ? .

Ukusuka kwi-URL, umncedisi unokwahlula ixabiso elingeniswe ngumsebenzisi apho:

isitshixo - indawo
