IIS重写dosnt允许/中断post请求

我在我的另一个非IIS web服务器前面有一个IIS实例，该服务器托管着一个站点，其中IIS正在执行一些AAR魔术，这很好，但是对于POST请求，由于某些原因，这似乎不起作用，这意味着非IIS web服务器上应用程序的任何ajax调用最终都会中断。有没有办法解决这个问题？下面是当前的规则设置

首先，尝试在iis中运行失败的请求跟踪。您是否尝试在没有iis arr反向代理的情况下发出post请求？确保应用程序在没有arr反向代理的情况下工作。您可以尝试一些故障排除步骤，如Fiddler跟踪、Winhttp跟踪和netmon跟踪。另外，使用反向代理时，请检查后端网站的日志。是否成功将post请求反向到后端网站？后端服务器是否正确处理请求？或者反向代理没有将某些数据传递到后端网站，从而导致后端网站报告错误？
