Error -26377 单用户多次/少量用户多次没有这个问题，大量用户会有
web_set_max_html_param_len("1024");
Action.c(56): Error -26377: No match found for the requested parameter "returncodeVar". Check whether the requested boundaries exist in the response data.
Also, if the data you want to save exceeds 4096 bytes, use web_set_max_html_param_len to increase the parameter size
经测试发现...
web_set_max_html_param_len("1024");语句应该写在web_reg_save_param(）之前，例如：
web_set_max_html_param_len("1024");
web_reg_save_param("returncodeVar",
"LB={\"returncode\":\"",
"RB=\"}",
"Ord=1",
LAST);
如果脚本中多次用到web_reg_save_param(）应该每处都加上这句web_set_max_html_param_len()
办法一不能解决的情况下，
解决办法如下：设置runt time setting中的internet protocol-preferences中的advaced区域有一个winlnet replay instead of sockets选项，选项后再回放就成功了!
Error -27740
Action.c(5): Error -27740: Overlapped transmission of request to "192.168.4.177" for URL "http://192.168.4.177:8080/" failed: WSA_IO_PENDING

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");

一、Step download timeout (120 seconds)
这是一个经常会遇到的问题，解决得办法走以下步骤：
1、修改run time setting中的请求超时时间，增加到600s,其中有三项的参数可以一次都修改了，HTTP-request connect timeout，HTTP-request receieve timeout，Step download timeout，分别建议修改为600、600、5000。run time setting设置完了后记住还需要在control组件的option的run time setting中设置相应的参数。
2、办法一不能解决的情况下，解决办法如下：
设置runt time setting中的internet protocol-preferences中的advaced区域有一个winlnet replay instead of sockets选项，选项后再回放就成功了。切记此法只对windows系统起作用，此法来自zee的资料。Error -27796
