HTTP GET AND HTTP POST

HTTP GET :

Let's say you have a page and want the user to click a link to view the first article in this series.

In this case a simple hyperlink is all you need.

<a href="http://coding-issues.com/Articles/741.aspx">Part I</a>

When a user clicks on the hyperlink in a browser, the browser issues a GET request to the URL

specified in the href attribute of the anchor tag. The request would look like this:

GET http://odetocode.com/Articles/741.aspx HTTP/1.1

Host: odetocode.com

HTTP POST :

Now imagine you have a page where the user has to fill out information to create an account. Filling out information requires <input> tags, and we nest these inputs inside a <form> tag and tell the browser where to submit the information.

<form action="/account/create" method="POST">

<label for="firstName">First name</label>

<input id="firstName" name="firstName" type="text" />

<label for="lastName">Last name</label>

<input id="lastName" name="lastName" type="text" />

<input type="submit" value="Sign up!"/>

</form>

When the user clicks the submit button, the browser realizes the button is inside a form. The form tells the browser that the HTTP method to use is POST, and the path to POST is /account/create. The actual HTTP request the browser makes will look something like this. 

POST http://localhost:1060/account/create HTTP/1.1

Host: server.com

firstName=Scott&lastName=Allen

Notice the form inputs are included in the HTTP message.
