plex requests

people may think that each request spends most of the time on downloading resources, let's see Blogjava resources Download Waterfall Graph (each color represents the stage corresponding to the above 5 stages):You may be surprised to see that the time spent in the waiting phase is much more than the actual download time, tell us:1. The majority of the time spent on each request is at other stages, not in the download resources phase2. Small resources will still take a lot of time at other stages

real-time interaction between C/S information 4. Can be encrypted, data security is high disadvantage: 1. The data that is transmitted must be parsed and translated into application-level data 2. The developer level requires 3. TTP protocol transmission, increased amount of development HTTP requests mainly have HTTP protocol, HTTP protocol-based SOAP protocol, common HTTP data request method has get and Post,web service advantages: 1.

1.httpclient is a toolkit that can send HTTP connections, including the ability to send post requests and get requests.An HTTP connection once has a return stream. HTTP is a two-way street. Only if the connection is made, there will be an output return stream.So when an HTTP connection is executed, the return value is the return stream of the HTTP connection.HttpResponse response = Client.execute (HttpPost);2.http send, the body can be written in Chin

Ajax requests use jsonp for cross-origin, ajax requests jsonp Cross-origin:Javascript has a single-source restriction. In short, different sources cannot interact with each other. so how to calculate the source is different? For example, if you access the server through A browser, you can only access the resources of server A (with the same domain name and port, in addition, the domain name and the correspo

PHP methods for simulating http requests and php requests This example describes how to simulate an http request in PHP. We will share this with you for your reference. The details are as follows: Method 1: Use php socket programming to directly send data to the interface to simulate post operations. Create two files: post. php and getpost. php. The post. php content is as follows: The content of getpost.

For more information about the differences between ajax synchronous requests and asynchronous requests, see. The differences between ajax synchronization and Asynchronization are as follows: Code 1: The Code is as follows: Synchronize = function (url, param ){Function createXhrObject (){Var http;Var activeX = ["MSXML2.XMLHTTP. 3.0", "MSXML2.XMLHTTP", "Microsoft. XMLHTTP"];Try {Http = new XMLHttpRequest;}

The problem with learning MVC today is how to differentiate whether a request is a GET request or a POST request, and I hope to share it with you.When I request a method of a controller class in a view, sometimes it is necessary to have a method of the same name, but to distinguish between the two methods. So I added [HttpPost] and [HttpGet] in front of the method to distinguish between a get or a POST request.[HttpPost]Public ActionResult Permissionson (formcollection form) {}[HttpGet]Public Ac

Prevent the tab page from repeatedly sending requests to the server, and the tab page repeatedly requests to the server Let's look at the figure. On the left is the enterprise tree, and on the right is a tab page based on enterprise changes. Features: 1. We hope that if the selected enterprise remains unchanged, we will request the server when switching the five tabs next to it. The following switch back a
