An http request is a class consisting of HTTP styles requests, request lines, request methods, request URL, header fields and body content. The most common methods that are used by a client in an HTTP request are as follows.

Ø  GET

Used when the client is requesting a resource on the web server. The GET method is the simplest and most frequently used request method. It is used to access the static resource, such as HTML documents and images. GET request can be used to retrieve dynamic information by including query parameters in the request URL.

Ø  HEAD

Used when the client is requesting some information about a resource but not requesting the resource itself.

Ø  POST

Used when the client is sending information or data to the server – for example filling out an online form (ie. Sends large amount of data to the server)

Ø  PUT

When the client is sending a replacement document or uploading a new document to the web server under the request URL.

Ø  DELETE

Used when the client is trying to delete a document from the web server, identified by the request URL.

Ø  TRACE

Used when the client is asking the available proxies or intermediate servers changing the request to announce themselves.

Ø  OPTIONS

Used when the client wants to determine other available methods to retrieve or process a document on the web server.

Ø  CONNECT

Used when the client wants to establish a transparent connection to a remote host, usually to facilitate SSL-encrypted communication (HTTPS) through an HTTP proxy.

Ø  PATCH

It is used to apply partial modifications to a resource.
