Redirection form IIS with web.config to PHP

I've wrote this file for redirection and I don't understand why the sixth redirection does not work. all the other ones do work.

I'm really new to IIS and ASP (and intend to keep myself like this :) ) but need some clarification about this so I could move on.

Your last rule (r6) is invalid. The URL pattern CANNOT include query string. Query String has to be matched separately, via conditions.

Here is correct rule:

<rule name="r6" stopProcessing="true">
    <match url="^articles/dynamic-web-articles\.aspx$" />
    <conditions>
        <add input="{QUERY_STRING}" pattern="page_id=55&amp;parent_id=0&amp;pgnm=%D7%97%D7%92%D7%99%D7%9D" />
    </conditions>
    <action type="Redirect" redirectType="Permanent" url="http://www.doctornestor.co.il/blog/%D7%93%D7%99%D7%90%D7%98%D7%94-%D7%91%D7%97%D7%92%D7%99%D7%9D/" />
</rule>
