在IIS URL重写模块字符串函数 [英] String Functions in IIS Url Rewrite Module

问题描述

在 IIS URL重写模块附带3内置的<一个href=\"http://learn.iis.net/page.aspx/465/url-rewrite-module-configuration-reference/#String_functions\"相对=nofollow>功能的：

* ToLower - returns the input string converted to lower case.
* UrlEncode - returns the input string converted to URL-encoded format. This function can be used if the substitution URL in rewrite rule contains special characters (for example non-ASCII or URI-unsafe characters).
* UrlDecode - decodes the URL-encoded input string. This function can be used to decode a condition input before matching it against a pattern.

的功能可以通过使用以下语法调用：
{FUNCTION_NAME：any_string}

现在的问题是：可以在此列表中引入的替换功能，这是可用于重写规则的动作或状态改变中值来延长

The question is: can this list be extended by introducing a Replace function that's available for changing values within a rewrite rule action or condition?

帧的问题另一种方式：有没有办法做到在使用这个模块来一个网址全局替换？

Another way to frame the question: is there any way to do a global replace on a URL coming in using this module?

看来你是仅限于使用常规的前pressions和反向引用来构建字符串 - 即没有查找/替换机制来替换的每个的的Y的{} REQUEST_URI， 的X实例，而不的了解多少实例存在。

It seems that you're limited to using regular expressions and back-references to construct strings - i.e. there's no search/replace mechanism to replace every instance of X with Y in {REQUEST_URI}, without knowing how many instances there are.

我已经在可扩展性的在2.0 RTW推出并没有看到这种引入任何光的手段。

I've had a quick glance at the extensibility introduced in the 2.0 RTW and don't see any 'light' means of introducing this.

推荐答案

看起来你必须实现自己的供应商，如下所示：

Looks like you have to implement your own provider as shown here:
