setupProxy.js for http->https with cookies

setupProxy.js

const proxy = require('http-proxy-middleware');

// Execute `copy(document.cookie)` in the console on the proxy site
// and paste into this string.
const cookies = '';

module.exports = function(app) {
  app.use(proxy('/api', {
    changeOrigin: true,
    cookiePathRewrite: true,
    cookieDomainRewrite: true,
    secure: false,
    rejectUnauthorized: false,
    onProxyReq: (proxyReq, req, res) => {
       proxyReq.setHeader('Cookie', cookies);
    },
    target: 'https://proxysite.com/',
  }));
};

Thanks for code snippet . I have tried the above code but it was giving error. Then i fixed that error with following piece of code.

  app.use(
    proxy('/api', {
      changeOrigin: true,
      cookieDomainRewrite: {
       "unchanged.domain": "unchanged.domain",
       "old.domain": "new.domain",
      "*": ""
      },
      secure: false,
      rejectUnauthorized: false,
      onProxyReq: (proxyReq, req, res) => {
        proxyReq.setHeader('Cookie', cookies);
      },
      target: 'https://proxysite.com/'
    })
  );
};```

Setting boolean true for cookiePathRewrite and cookieDomainRewrite  is not working.
