使用IIS6和Php重写URL

I have two websites very similar on two servers : 1 using IIS6 and the other using IIS7

Both are in Php.

For the one with IIS7 I used a web.config with that syntax :

<configuration>
<system.webServer>  
    <rewrite>
        <rules>
           <rule name="Rule1">
               <match url="^Test?$"></match>
               <action type="Rewrite" url="/test.php"></action>
           </rule>
       </rules>
    </rewrite>
</system.webServer>
</configuration>

It works fine. But I can't do it with IIS6

Constraints :

• II6 can't be upgraded

• I wan't to keep a web.config method (with Xml) : Ionics Isapi use Htaccess

• Php

Are there any other methods?

Thanks !
