HTTP (Hypertext Transfer Protocol)
Since data is 0's and 1's, both sides of a transfer use protocols to translate that data to messages.
HTTP is the language clients, such as Web browsers, and Web servers use to transfer Web pages.
HTTP Requests¶
A browser makes a request for a resource and specifies that it is using HTTP.
* The browser also specifies the type of request to tell the server what it's trying to do.
* The two basic request types are GET and POST.
GET Request¶
A GET request is intended to retrieve a document.
* GET should only retrieve data.
* GET requests remain in the browser's history.
* Visiting a web page is usually a GET request.
POST Request¶
A POST request submits data to a server to be processed.
* POST is intended for providing information to a server that might be used by the server to modify content on the site.
* Submitting a form on a site should be a POST request.
Server Response¶
The server, also using HTTP, responds to the request with the data.
* The browser knows how to read the data, and can display it as a web page.
