这篇文章介绍了LoadRunner与WEB页面交互的两个层次，实际上就是解析了LoadRunner的两种WEB脚本协议 – Web（HTTP/HTML）和Web（Click and Script）的区别。值得参考。

LoadRunner basically allows two approches for load testing your web application.

you can see between user and web server there are mainly 2 layers:

- Layer 1 is where user interacts with the browser by e.g. clicking a button, selecting values from the list or submitting a form

- Layer 2 is where browser communicates with web server which includes:

creating and sending HTTP requests to the web server based on user’s actions

receiving HTTP responses from the web server

rendering HTTP responses, forming an UI and displaying it to the user
