Web page transmission method, web page display device and system including the device

Abstract

The present application provides a web page transmission method, wherein resources in the web page are pre-configured with priorities. The method includes: the browser obtains the source code file of the web page from the web server; the browser parses the source code file to extract the priority of the resource; the browser sends a resource request to the web server, and the The request carries the priority of the resource; and the web server sends the resource to the browser according to the priority order of the resource. According to this application, the priority of resources in the webpage is directly pre-configured by the webpage developer, which has a more flexible and universally adaptable serialization of infinite parallel data streams. Page rendering effect.

Description

technical field [0001] The present application relates to the field of data communication, and more specifically, to a web page transmission method, a web page display device, and a web page transmission and display system. Background technique [0002] With the increasing development of computer network technology, people can access millions of websites and billions of web pages through the Internet. When the user wishes to visit a certain web page, he can open a browser and input the URL of the web page in the address bar. The browser sends a request for accessing the web page to the web server based on the URL. The web server sends the source code file (eg, HTML file) of the web page to the browser in response to the browser's request. After receiving the source code file of the web page, the browser will parse it, and then send resource requests to the web server for each resource (such as Javascript file, picture, text, style sheet, etc.) in the web page, and After o...

Problems solved by technology

[0007] However, the solution's support for priority depends largely on the control components returned by the server, and the browser needs to cooperate well with it to complete resource priority scheduling

And in this solution, the executor of priority scheduling is placed in the browser, which undoubtedly adds more complex processing logic to the browser's page loading process. Considering the processing capacity of the terminal device where the browser is located, it may increase page load delay

At the same time, this solution does not consider the situation of concurrent requests for resources in a page. In today's web page browsing, it is very common to establish multiple TCP connections for a host to make concurrent requests for resources. Resources that are purely controlled by the browser are preferred. Scheduling at the same level, it is impossible to achieve synchronous control between TCP connections. Resource requests initiated in the order of priority do not necessarily arrive at the server in the order they are sent, and even if they arrive at the server in order, they may not be responded to by the server in order. Obviously, this solution cannot To ensure that the browser obtains the resources in the order of the expected priority in the actual page browsing, it cannot guarantee the strict priority of the resources described in the scheme
