How can I forward a subdirectory of my Gigalixir application domain to a different application completely outside of Gigalixir without using a subdomain to serve the content?

Gigalixir is not appropriately setup as a reverse proxy for assets outside of our infrastructure. QuotaGuard (www.quotaguard.com), our partner company, is a proxy company that can provide users with an inbound proxy or also known as a reverse proxy.

The QuotaGuard Static ​service’s (not Shield) Micro Plan or higher allows for inbound proxy. While it will not have an option for the path based routing in the IU, we can definitely help users set it up.
