Message Code 27740
Overlapped transmission of request to '%1' for URL 'URL' failed.
The transmission of data to the server failed. It could be a network, router, or server problem. The word Overlapped refers to the way LoadRunner sends data in order to get a Web Page Breakdown.
Troubleshooting
Add the following statement to the beginning of the script to disable the breakdown of the "First Buffer" into server and network time: web_set_sockets_option("OVERLAPPED_SEND", "0");
web_set_sockets_option("OVERLAPPED_SEND", "0");

这个问题不多遇见，一般是由于下载的速度慢，导致超时，所以，需要调整一下超时时间。
解决方法：在脚本最前面插入web_set_sockets_option("OVERLAPPED_SEND", "0");
