Rewrite url to include additional directory

I have a sub-domain setup and working fine until the URL to display a file is called.  The URL is in the following form:

http://111.222.33.4444/temp/filename.pdf

I need it to be re-written so that it includes the sub-domain directory in the URL like this:

http://111.222.33.4444/test/temp/filename.pdf

I have tried to create a rule using URL rewrite, but it is not working correctly.  Here is the rule I have written:

<rewrite>

<rewriteMaps>

   <rewriteMap name="http://111.222.33.444/temp">

    <add key="/temp/" value="/test/temp/" />

   </rewriteMap>

  </rewriteMaps>

  <rules>

   <rule name="Rewrite rule1 for http://111.222.33.444/temp" enabled="true">

    <match url="(/temp/)(.+)" />

     <conditions>

      <add input="{http://111.222.33.444:{PATH_INFO}}" pattern="(/temp/)(.+)" />

     </conditions>

    <action type="Rewrite" url="{R:1}" appendQueryString="true" logRewrittenUrl="true" />

   </rule>

  </rules>

 </rewrite>

Can anyone help me figure out how to make this work?

Thanks in advance...
