HTTP protocol analysis of ASP. NET Programming Model

HTTP request of ASP. NET Programming Model HTTP protocol

First create An aspx page drag up only one button and a text box, open Fiddler this is a Microsoft employee developed HTTP debugging tool, http://www.fiddlertool.com/), and then browse the page just created. View Fiddler. We will see:

 

The content in the above box is actually the content submitted to the server by the browser after you press enter, and the server obtains the information and parses it, then, we will provide you with the corresponding page based on your request. Let's briefly introduce the content here:

GET: it follows the location of a webpage. The server accepts the request and returns the requested page. In addition to the page location as a parameter, the request can also follow the protocol version such as HTTP/1.0 as a parameter to send more information to the server.

Accept-Language: Current browser Language

Host: specifies the Intenet Host and port number of the requested resource, which must represent the location of the original server or gateway of the request url. The HTTP/1.1 request must contain the Host Header domain; otherwise, the system returns the status code 400.

User-Agent: contains the User information of the request, which identifies the browser type of the request.

Connection: close a Connection or keep a Connection valid.
