Send Errors to a remote browser in IIS7

I have a IIS7 site hosted with Godaddy...needed to see ASP error and PHP errors.  Here is the entire web.config file.

<?xml version="1.0"?>
<configuration>
  <system.webServer>
      <httpErrors errorMode="Detailed"/>
      <asp scriptErrorSentToBrowser="true"/>
  </system.webServer>
</configuration>
