Url Rewrite with Web.config not working with IIS express - asp.net

Question

I need to use Url Rewriting, so I made a test case, in Web.config, to check if it's working:
Web.config:
<system.webServer>
<rewrite>
<rules>
<rule name="Fail bad requests">
<match url=".*"/>
<action type="AbortRequest" />
</rule>
</rules>
</rewrite>
... other stuff
</system.webServer>
I was expecting any localhost:3285 to abort and fail, but it entered correctly.
I'm using Url Rewrite with IIS Express.

I am guessing your problem is browser caching. I have found that if I open a web page in IE, then add URL rewrite rules (requires stopping IIS express), then open the same page again in IE it still loads the page (and it appears the abort rule is not being applied). But, if I clear the IE browser cache and refresh the page the abort occurs.
Here is a full Web.config example that works for me
<?xml version="1.0" encoding="utf-8"?>

<rule name="Fail bad requests">

</rules>

Your example should work because the URL rewrite module is built into the current version of IIS Express:
