LoadRunner测试一个简单的AJAX例子
测试的例子：
http://www.degraeve.com/reference/simple-ajax-example.php
如果用WEB(HTTP/HTML)协议来录制，则AJAX行为会被录制成web_submit_data函数：
Action()
{
web_add_cookie("__utma=251078419.1213328951.1265334283.1265334283.1265339393.2; DOMAIN=www.degraeve.com");

如果用AJAX（Click and Script）协议来录制，则脚本会短很多3个web_url函数被替换成了一个web_browser函数，多个web_add_cookie函数也被一个web_add_cookie_ex函数替代了，ajax行为会被录制成web_edit_field和web_button函数（Click & Script的脚本编写方式更倾向于从用户行为的角度出发，例如在输入框输入、按下按钮等）。
Action()
{
web_add_cookie_ex("Cookie=__utma=251078419.1213328951.1265334283.1265339393.1265339466.3; domain=degraeve.com; path=/", ENDITEM,

但是，似乎这样录制的HTTP请求内容会少一些，例如对以下URL的请求不能在回放日志中找到：
http://www.geekchart.com/api.php?action=getchartdata&username=steve
在使用WEB(HTTP/HTML)协议来录制时是这行脚本：
web_url("api.php",
"URL=http://www.geekchart.com/api.php?action=getchartdata&username=steve",
"Resource=0",
"RecContentType=text/html",
"Referer=http://www.geekchart.com/img/geekchart.swf?username=steve",
"Snapshot=t7.inf",
"Mode=HTML",
LAST);
