Hello! I am looking for assistance with static redirects in the web.config file.

I am publishing a new website for a customer, same domain, just need to keep SEO cred by redirecting their old "[domain].com/contact.php" url to the new "[domain].com/contact/" (and about 8 other pages like that).

I'm used to using a rewritemap.config in the root folder, and then having the configSource here:

<rewrite>
     <rewriteMaps configSource="rewritemaps.config" />     
      <rules>
            <rule name="Redirect rule1 for Redirects">
              <match url=".*" />
              <conditions>
              <add input="{Redirects:{REQUEST_URI}}" pattern="(.+)" />
              </conditions>
              <action type="Redirect" url="{C:1}" appendQueryString="false" />
      </rules>
    </rewrite> 

However, the syntax has changed and what I've tried didn't take for some reason. Any help is appreciated!
