录制了一段loadrunner测试脚本，但是回放的时候总是跑不通，总是报错12002。报错的位置是在请求ajax文件的web_custom_request函数处。
web_custom_request("ReverseAjax.dwr", "URL=http://10.133.210.49:9011/khyx/dwr/call/plainpoll/ReverseAjax.dwr", "Method=POST", "Resource=0", "RecContentType=text/javascript", "Referer=http://10.133.210.49:9011/khyx/um/umtmenu/prepareAll.do", "Snapshot=t70.inf", "Mode=HTTP", "EncType=text/plain", "Body=windowName=main\ncallCount=1\nbatchId=2\ninstanceId=0\npage=%2Fkhyx%2Fum%2Fumtmenu%2FprepareAll.do\nscriptSessionId=3vg0y$s*wR9Y3tSH81LnfXFslBk/yLFslBk-iLQy*g2fy\npartialResponse=0\n", LAST);
