In the previous analysis of the request, the writeline operation in at_send_command_full_nolock was terminated, because the operation to write the command to the hardware device was completed here, and the next step was to wait for the hardware response, that is, the response process.

Reponse Headers
In theory, all response header information should be in response to the request header. But for the sake of efficiency, security, and other considerations, the corresponding response header information is added, which can be seen from:
Cache-control:must-revalidate, No-cache, private. This value tells the client that the server does not want
Remember: the operations on the affected system may change the existing evidence or lead to the loss of sensitive information!

Vue Data Response principleThe core of Vue.js includes a set of "responsive systems". "Responsive" means that when the data changes, Vue notifies the code that uses that data. For example, data is used in view rendering, and the view is automatically updated when the data is changed.To give a simple example, for a template:{{Name}}Create a Vue component:var New Vue ({ ' #root ', data: { ' Luobo '} })After the code executes, the corresponding loc

How many cars can I get in 1 seconds? tps=102, how long does it take for each car to respond? reponse time = 13, change to 20 cars, how few per second? How long is the response time for each car? TPS = 10,reponse time = 14, ingress expands to 20, how few can I enter per second? How long is the response time fo

The user's interactive operation (interaction) drives the Web site. It is important to understand how to handle response information, especially when using new forms of interaction (such as Ajax). Kris Hadloc explains the nature of the AJAX request-response process, and you should be aware of the content to better interoperate with the user.

Sometimes, the network administrator can configure an internal network to implement communication between a single host and other hosts at different levels. A single Internet Protocol (IP) address may represent many devices that have opened ports on the internal network.
