loadrunner测试单点登陆的问题

问题：
在录制了单点登陆后，单台机器回放没有问题，用了负载均衡器之后回放报错，错误如下：
Action.c(847): Error -27778: SSL protocol error when attempting to connect with host "192.168.1.41"   [MsgId: MERR-27778]
Action.c(847): Warning -26000: Empty or no response for URL="https://192.168.1.41:8443/cas/remotelogin"   [MsgId: MWAR-26000]
Action.c(847): web_submit_data("remotelogin") highest severity level was "ERROR", 0 body bytes, 0 header bytes   [MsgId: MMSG-26388]
Action.c(847): Notify: Transaction "index3" ended with "Fail" status (Duration: 4.0039).

解决方案：
在virtual user generator 内，vuser->run-time settings->preferences->advanced里勾上WININET replay instead of Sockets。
