The essential difference between post and get request method of network engineering

The essential difference between a post and a GET request method:

First: Get is used for information acquisition, it is secure (here the meaning of security refers to non-modified information), and post is used to modify the resources on the server request

Second: The data for the GET request is appended to the URL, and the post submits the data to the body of the HTTP message entity, so the security of the post is higher than the security of the Get

Third: For the POST request data volume than get high is a misunderstanding, really affect the amount of data requested is the server, the server limit is the real reason.
