1. The basic difference between get() and post()
1.get adds the parameter data queue to the URL pointed to by the ACTION attribute of the submitted form. The value corresponds one-to-one to each field in the form, which can be seen in the URL. arrive. Post uses the HTTP post mechanism to place each field in the form and its content in the HTML HEADER and transmit it to the URL address pointed to by the ACTION attribute. Users cannot see this process.
2. For the get method, the server side uses Request.QueryString to obtain the value of the variable. For the post method, the server side uses Request.Form to obtain the submitted data. Parameters in both ways can be obtained using Request.
3. The amount of data transferred by get is small and cannot be larger than 2KB. The amount of data transmitted by post is relatively large and is generally unrestricted by default. But in theory, it varies from server to server.
4.get has very low security, while post has high security.
