standards or standards revisions see regularly updated.
The main function of a web browser is to allow the
consultation information available ("resource" in the Web terminology) on the
World Wide Web. The main stages of the consultation of a resource are:
· The user gives to the web browser the web address
resource to consult. There are three ways to give a web address:
- Typing yourself the web address in the browser address
bar;
- Choose a resource in the list of favorites (or bookmark this
page or bookmark), knowing that every favorite is associated a web address;
- Follow a hyperlink, knowing that each link is associated a
web address.
· The browser connects to the web server hosting the
resource referred and downloads. The communication protocol generally used is
http.
· Rendering engine of the browser treats this resource,
downloads any associated resources and displays the result on the user's
screen.
Web browsers will be fully customary in the process of
developing this web application for both tests for debugging. And those used
are the two most popular browsers such as Google Chrome and Mozilla Firefox.
