Launch remote website through rdm server

Hello all,
I'm facing an issue where I cannot seem to find what I need.
Situation is as follows:
Local machine is connecting to a RDM instance on a remote server (through vpn). That part is working fine.
Through the RDM server, I use RD gateway with a user/pass to connect to remote desktops that my machine cannot access, but the remote RDM server can access.
Besides the RDP sessions, I would also like to make connection to a remote website. Again, the RDM server can reach this site, but my local machine cannot.
I can't seem to find anything similar to rd gateway for http(s) traffic. Is that option in RDM? Or do I need to be creative with tunneling though SSH sessions or something like that?

Regards,
Frank
