Proxy reverse

Hello guys, I need a HELP. My own website hosted on azure like WEB APPLICATION. there are my database and application. Now I need to perform a redirection to an external address + port that would look like this: When someone clicks a link on my site (https://mysite.com) it would be redirected to https://200.200.200.10:8000,   I would like this address not to appear for the user and only https://mysite.com/folder

In Apache Server that would be reverse proxy

ProxyPass                /folder       http://200.200.200.10:8000/folder
ProxyPassReverse         /folder       http://200.200.200.10:8000/folder.

 

Could someone help me do this in the azure?
