I guess OP has figured out a solution by now, considering this post is like 10 years old. But for anyone who bumps into this like me:

You need to setup an outbound rule I believe by the following steps:

1. Open IIS Manager
2. Select your Website
3. Open URL Rewrite module
4. Add a new outbound rule
5. Select the necessary options, but most importantly, set the pattern to something like ^/(.*) which accepts any string after /
6. Set the action type as Rewrite
7. Set the Action Properties-> Value like https:///training/{R:1}

Apply and test. This should rewrite the responses with the /training to navigate your intended page.
