URL Rewriting with Query Strings using IIS URL Rewrite Module - iis-7

Question

I am trying to rewrite a url such as:
new_membership?R=1&I=2
to:
agent_new_membership.aspx?R=1&I=2
but I am getting an error reading: "HTTP Error 404.0 - Not Found"
This is the web.config code I am using:
<rewrite>
<rewriteMaps>
<rewriteMap name="Redirects">
<add key="/administration" value="/administration_main.aspx" />
<add key="/change_admin_password" value="/admin_change_password.aspx" />
</rewriteMap>
</rewriteMaps>
<rules>
<rule name="New Membership" stopProcessing="true">
<match url="^new_membership?R=(\d+)&I=(\d+)$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="agent_new_membership.aspx?R={R:1}&I={R:2}" />
</rule>
<rule name="Redirect rule1 for Redirects">
<match url=".*" />
<conditions>
<add input="{Redirects:{REQUEST_URI}}" pattern="(.+)" />
</conditions>
<action type="Rewrite" url="{C:1}" appendQueryString="false" />
</rule>
</rules>
</rewrite>
What am I doing wrong?
Thanks in advance.

This should work for you:
<rule name="TestRule" stopProcessing="true">
<match url="^new_membership\?R=(\d+)&I=(\d+)$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="agent_new_membership.aspx?R={R:1}&I={R:2}" />
</rule>
