(1) In the client, the data submitted by the Get URL manner, data can be seen in the URL; the POST mode, data is placed in the HTML HEADER submitted.
Data (2) GET submission of only 1024 Byte most, while POST is no such restriction.
(3) security issues. As in (1) mentioned that the use of Get, the parameters will be displayed in the address bar, and the Post will not. So, if these data are Chinese data and non-sensitive data, then use the get; if the user input data is not Chinese characters and contain sensitive data, or use the post as well.
Form submission and get the difference in the way post summarized the following points:
(1) get the data is acquired from the server, post data is transmitted to the server.
(2) For the form submission, the server can only be used to acquire data Get Request.QueryString submission to the data submitted by the Post manner can only be used to obtain Request.Form.
