SignalR：Connection（）时404响应的故障排除建议

Question

我在QA环境中的连接时遇到404 - Not Found Error。我们的开发集成环境中没有相同代码的问题。 我看过这里报道的其他404，并没有找到一个好的比赛。 运行fiddler，传出请求在两种环境中都非常相似。

有关如何进一步排除故障的任何建议？感谢。

Answer 1

这里的另一个人找到答案，我将分享。 在IIS7中，有一个名为“URLRoutingModule-4.0”的设置。 “编辑托管模块”对话框还包含一个复选框“仅对ASP.NET应用程序或托管处理程序的请求调用”。取消选中该复选框。

此设置位于“默认网站”级别，双击功能视图中的“模块”以获取模块列表，双击行项“URLRoutingModule-4.0”以启动“编辑管理模块”对话框。
