We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 - File or directory not found."

最好的问候.

推荐答案

您遇到此错误的原因是 IIS7 出于安全原因引入了新的 URL 过滤规则.因此，作为 URL 中安全原因的一部分，默认情况下会阻止+"号.

The reason why you are facing this error is that IIS7 has introduced new URL filtering rules for security reasons. So '+' sign is blocked by default as part of security reason in URL.

要解决此问题，您必须在 web.config 文件中设置 allowDoubleEscaping="true".这是执行此操作的标签.

To resolve this issue you have to set allowDoubleEscaping="true" in web.config files. Here is the tag to do that.

<system.webServer>
<security>
  <requestFiltering allowDoubleEscaping="true">
  </requestFiltering>
</security>
