asp.net – XMLHTTP请求的经典ASP错误
我在IIS 7.5上运行经典ASP和ASP.net 4.0.
在我的经典ASP代码是这段代码: ' Process @ alerts Dim objHttp set objHttp = Server.CreateObject("Microsoft.XMLHTTP") objHttp.open "POST",strSiteRoot & "handlers/forumalerts.ashx?",false objHttp.setRequestHeader "Content-type","application/x-www-form-urlencoded" objHttp.Send "topicID=" & lngTopicID & "&threadID=" & lngLastPostID set objHttp = nothing 这是向ASP.net ASHX处理程序发送请求.运行时,它会在最终发送错误消息之前挂起很长时间:
我已经检查了它发布到的URL,它存在且正在运行.发送的数据也是正确的. 在我全新安装Windows 7之前,它运行良好.由于重新安装它,并再次设置IIS这段代码失败,让我相信它是一个权限/身份错误. 有谁能告诉我是什么原因造成的?我有3个应用程序池: ASP.net v4.0 (Integrated) (ApplicationPoolIdentity) ASP.net v4.0 Classic (Classic) (ApplicationPoolIdentity) DefaultAppPool (Integrated) (NetworkService) 谢谢你的帮助! 编辑:我在日志中发现了这个错误: Event code: 3005 Event message: An unhandled exception has occurred.

如果我理解正确,您正在向与呼叫服务器相同的服务器发出请求.
