Hypertext Transfer Protocol (HTTP) Question:

GET is the simplest type of HTTP request method; the one that browsers use each time you click a link or type a URL into the address bar. It instructs the server to transmit the data identified by the URL to the client. Data should never be modified on the server side as a result of a GET request. In this sense, a GET request is read-only, but of course, once the client receives the data, it is free to do any operation with it on its own side - for instance, format it for display.
