Design now talk about book.htm, let everyone know the role of the input form, its action object is itself, book.asp (wait for a while to rename book.htm to book.asp) This file, that is. After the form is submitted, it is handled by itself. In this form, there are several text input boxes, which are name,sex,from,url,email, and multiple lines of text input boxes comments.
Now rename book.htm to book.asp and add ASP code to the file. as follows: (single quotation marks represent an ASP's analysis, the compiler is not processed.)
*book.asp
<% @language = "VBScript"%>

"To determine the request, when the client requests the file, such as direct input URL: http://active.silversand.net/index.htm This way, you will produce a GET request information. When the form is submitted (the form is set to post), it will produce a POST request, and now judge whether the book.asp file is the user to open the page in the browser, or the user submits the data this action, in order to process.
