Preserving original domain in browser bar instead of being redirected and showing target domain

[suan]

I have a very straightforward setup just wanting to transparently proxy https://mydomain.com/blog/pricing to https://otherdomain.com/pricing, but have the browser bar show mydomain.com, NOT otherdomain.com – whatever I try I can't seem to get it to work, and just get redirected instead.

What am I missing?

const proxie = createProxyMiddleware({
  target: 'https://otherdomain.com',
  changeOrigin: true,
  secure: false,
  pathRewrite: {'^/blog' : ''},
});

app.use('/blog', proxie);

I set "changeOrigin: false" and that seemed to solve that problem for me.
