(In the first lecture of the column, I said that in order to realize the vision of building a hyperlink document system on the Internet, Tim Berners Lee invented the world wide web and used HTTP protocol to transmit "hypertext", so that people can share information freely all over the world."Hypertext" contains "hyperlinks", which can jump from one "hypertext" to another "hypertext", which is a fundamental change to the traditional linear structure document.The ability to jump anywhere on the web using "hyperlinks" is also a key feature of the world wide web. It connects documents scattered all over the world into a complex network structure. Users can click links and switch pages at will. In addition, the browser provides "forward", "backward", "bookmark" and other auxiliary functions, which makes it more convenient for users to jump between documents, more initiative and interaction.So, what is the jump when clicking on the "link" of the page? Specifically, for example, what happens when you click the "download" link on the home page of nginx?Combined with the previous lessons, think a little and give you the answer: the browser first parses the URI in the link text.)
