• Two HTTP Request Methods: GET and POST

    The Hypertext Transfer Protocol (HTTP) is designed to enable communications between clients and servers.

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

     

    A web browser may be the client, and an application on a computer that hosts a web site may be the server.

    Example: A client (browser) submits an HTTP request to the server; then the server returns a response to the client. The response contains status information about the request and may also contain the requested content.

    Two commonly used methods for a request-response between a client and server are: GET and POST.

    GET – Requests data from a specified resource
    POST – Submits data to be processed to a specified resource

    Some other notes on GET requests:

    GET requests can be cached
    GET requests remain in the browser history
    GET requests can be bookmarked
    GET requests should never be used when dealing with sensitive data
    GET requests have length restrictions
    GET requests should be used only to retrieve data

    Some other notes on POST requests:

    POST requests are never cached
    POST requests do not remain in the browser history
    POST requests cannot be bookmarked
    POST requests have no restrictions on data length
