the web.config with the rewrite rule is located in the root of the IISRewriteURL asp.net 3.5 web application on my pc.
the rewrite rule here is taken from the system.webserver section of that file...
<rewrite>
<rules>
<rule name="RedirectUserFriendlyURL1" stopProcessing="true">
<match url="^iisrewriteurl/content\.aspx$" />
<conditions>
<add input="{REQUEST_METHOD}" negate="true" pattern="^POST$" />
<add input="{QUERY_STRING}" pattern="^id=([^=&]+)$" />
</conditions>
<action type="Redirect" url="iisrewriteurl/content/{C:1}" appendQueryString="false" redirectType="Permanent" />
</rule>
<rule name="RewriteUserFriendlyURL1" stopProcessing="true">
<match url="^iisrewriteurl/content/([^/]+)/?$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="iisrewriteurl/content.aspx?id={R:1}" />
</rule>
</rules>
</rewrite>
also, here is the wildcard script map i added via the handler mappings section (which made no difference)...
<add name="Wildcard Map for Rewrites" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="None" preCondition="classicMode,runtimeVersionv2.0,bitness32" />
