Add URL rewrite rule on root website for specific URL

Is it possible to apply a URL rewrite based on a matching URL after my website name? So say I have a rule on http://foo:8080 that enables me to go to http://foo:8080/ and that would rewrite to http://too. Is there a way to say that if I access http://foo:8080/bar it will take me to http://too/bar but have the rule on the website foo without any applications underneath it?

This would enable multiple rules on one site to reroute based on where I navigate to in the first place rather than setting up multiple applications for each rewrite rule.

I hope this makes sense, if it doesn't but you think you have an answer please let me know and I'll try to be more clear.

Thanks

Thanks to @MisterSmith for pointing me in the right direction I found the answer to be the below, this also allows for http or https. My config now looks like the below:

 <rewrite>
        <rules>
            <rule name="Rule" stopProcessing="true">
                <match url="^bar/(.*)" />
                <action type="Rewrite" url="{C:1}://too:8080/bar/{R:1}" />
                <conditions>
                    <add input="{CACHE_URL}" pattern="^(https?)://" />
                </conditions>
            </rule>
        </rules>
    </rewrite>

The rule is set on the website "foo" and now when I go to http://foo/bar/blahblahblah I get a response from http://too:8080/bar/blahblahblah
