Difference and use of Get and post
The post and get differences in HTML, is not using the Get method with Post can do?
HTTP defines different ways to interact with the server, with 4 basic methods, namely get,post,put,delete. URL full name is a resource descriptor, we can think: a URL address, which is used to describe a network of resources, and HTTP get,post,put,delete corresponding to this resource, change, increase, delete 4 operations. Here, you should have a general understanding, get is generally used to get/query resource information, and post is generally used to update resource information. The following points are described:
1. Get is the data that is fetched from the server and post is the data sent to the server.
2. Get is the URL where the parameter data queue is added to the Action property of the submission form, and the value corresponds to the field one by one in the form, which is visible in the URL. Post is the HTTP post mechanism that places the fields within the form with their contents in the HTML header, along with the URL address referred to by the Action property. The user does not see the process.
3. For Get mode, the server side uses Request.QueryString to get the value of the variable, and for post, the server side uses Request.Form to obtain the submitted data.
4. Get transmits a small amount of data, cannot be greater than 2KB. Post transmits a large amount of data, which is generally not restricted by default. In theory, however, the maximum amount of IIS4 is 100KB in 80KB,IIS5.
5. Get security is very low, post security is high. But the execution efficiency is better than the Post method.
6. In ASP, the server obtains the GET request parameter with Request.QueryString, obtains the POST request parameter with the Request.Form. In JSP, with Request.getparameter (\ "xxxx\") to obtain, although JSP also has the request.getquerystring () method, but the use of more trouble, such as: Pass a test.jsp?name= HYDDD&PASSWORD=HYDDD, with
