When should the HTTP method GET be used?

When should the HTTP method GET be used?

GET is used for viewing something, without changing it, while POST is used for changing something. For example, a search page should use GET to get data while a form that changes your password should use POST . Essentially GET is used to retrieve remote data, and POST is used to insert/update remote data.

What is the purpose of HTTP request?

An HTTP request is made by a client, to a named host, which is located on a server. The aim of the request is to access a resource on the server. To make the request, the client uses components of a URL (Uniform Resource Locator), which includes the information needed to access the resource.

How does HTTP work?

  • GET requests a specific resource in its entirety.
