HTTP is effective communication for requests and responses between clients and servers. The message that is sent by a client to a server is what is known as an HTTP request. Client can send requests with various methods by the following table.
| Method | Description |
|---|---|
| GET | GET is the most used requests in HTTP request methods. GET is used to request and retrieve information from the server. Requests using GET should only retrieve data. |
| HEAD | HEAD is similar to GET but it transfers the status line and header section without having message-body in the response. |
| POST | POST is used to send data to the server to create or update a resource by using HTML form. |
| OPTIONS | OPTIONS is used to indicate the communication options for the target resource. |
| PUT | PUT is similar to POST and the PUT method replaces all current representation of the target resource with the request. |
| DELETE | DELETE is used to delete current representations of the target resource indicated by a specific URI. |
| TRACE | TRACE is similar to POST and PUT but it performs a message loopback test along the path to the target resource. |
| PATCH | PATCH is similar to POST and PUT and the main purpose of PATCH is used to partially modify the resource. |
