I'm developing an app, let's call it app A, which is embedded within another app, app B.
App A is embedded in app B as an iframe, and I regularly visit them both in my web browser for development. Let's say that app A is accessible via https://app-a.com and app B https://app-b.com.
Let's also say I'm running a server serving app A on my dev machine and thus it's accessible via localhost:3000.
I'd rather not start up app B on my dev machine, due to sluggish hardware, instead I would like all requests to https://app-a.com to proxy to http://localhost:3000 inside my web browser (which happens to be Chrome), such that I can visit https://app-b.com, it would make some HTTP requests to https://app-a.com, which on my dev machine would reach not https://app-a.com but localhost:3000.
Is this possible? I'm running macOS 10.14.5.
