What is HTTP?

The Hypertext Transfer Protocol (HTTP) is designed to ensure communication between the client and the server.

HTTP works as a request-response protocol between the client and the server.

A Web browser might be a client, and a network application on a computer might be a server-side.

Example: the client (browser) submits an HTTP request to the server, and the server returns a response to the client. The response contains status information about the request and what might be requested.

Two methods of HTTP request: GET and POST

In the request-response between the client and the server, the two most commonly used methods are: GET and POST.

• GET-Requests data from the specified resource.
• POST-submits the data to be processed to the specified resource

GET method

Note that the query string (name/value pair) is sent in the URL of the GET request:

/test/demo_form.asp?name1=value1&name2=value2

Some additional comments about the GET request:

• Get requests can be cached
• GET requests remain in browser history
• Get requests can be bookmark-Favorites
• GET requests should not be used when handling sensitive data
• Get request has a length limit
• GET requests should only be used to retrieve data

POST method

Note that the query string (name/value pair) is sent in the HTTP message body of the POST request:

Post/test/demo_form.asp http/1.1host:w3schools.comname1=value1&name2=value2

Some additional comments about the POST request:

• POST requests are not cached
• POST requests are not persisted in browser history
• POST cannot be bookmarked
• POST request has no requirement for data length
