如何使用IIS7 URL重写模块重定向到应用程序根目录？

Question

I have tried:

1) I tried empty string first:

<action type="Redirect" url="" redirectType="Permanent" appendQueryString="false" />

Result:

HTTP 500.52 - URL Rewrite Module Error.
The substitution URL for the current action cannot be empty.

2) Maybe I should omit the url attribute:

<action type="Redirect" redirectType="Permanent" appendQueryString="false" />

Same result:

HTTP 500.52 - URL Rewrite Module Error.
The substitution URL for the current action cannot be empty.

3) What about the ASP.NET way:

<action type="Redirect" url="~" redirectType="Permanent" appendQueryString="false" />

Tries to redirect to {APP_ROOT}/~ .

4) Last try:

<action type="Redirect" url="/" redirectType="Permanent" appendQueryString="false" />

As expected, it redirects to the root of the server...

I'd like to find some clean generic solution. (I cannot use some concrete /myCurrentAppPath .)

Answer 1

这效果更好：

<action type="Redirect" url="." redirectType="Permanent" appendQueryString="false" />

Answer 2

现在尝试这个，它不干净，但它的工作原理：

<action type="Redirect" url="?" redirectType="Permanent" appendQueryString="false" />
