multiple domain exceptions with 2nd level sub domains

[datpham23]

Is this a Feature or Bug?

Bug

Current behavior:

I want to test an app deployed at https://apphost.lab.domain.com.

1. When visiting my app https://apphost.lab.domain.com i'm redirected to an internal single sign on (SSO) at https://sso-host.dc1.domain.com
2. I log in and then i'm redirected back to my app https://apphost.lab.domain.com.
3. When I issue the command cy.visit('/some-path') I run into the multiple domain exceptions.

"...The previous domain you visited was: 'https://sso-host.dc1.domain.com'
You're attempting to visit this new domain: 'https://apphost.lab.domain.com' ..."

Desired behavior:

Should be able to issue cy.visit('/some-path') without exception.

How to reproduce:

Test code:

cypress.json
{
  "baseUrl" : "https://apphost.lab.domain.com/"
}

describe('Test', ()=>{
  before(()=>{
    cy.visit('/');
   //Redirected to single sign on page
    cy.get('#username').clear().type(Cypress.env('userName'));
    cy.get('#password').clear().type(Cypress.env('userPassword'));
    cy.get('#submit').click();
   //after logging in i'm redirected to my app at https://apphost.lab.domain.com/
  });

  it('show /my-page', ()=>{
    cy.visit('/my-page');  //exception occurs
  });

Additional Info (images, stack traces, etc)

Even though the sso host and app host is in the same sub domain i'm still seeing the multiple super domain exception.
Ideally we should just allow multiple super domains. Due to how our SSO work we can only be authenticated going through the browser, we can't simply make cy.request() to grab the token/cookie and manually set it our session.

The subdomain parsing is the same problem as this here: #802

So it would just "work" once we fix that issue.

As for the cy.request not working I am very curious. It's impossible for a webserver to know where traffic is coming from. In order to try to distinguish traffic it can only look at the headers of a request.

So whatever that is - you can just set in cy.request itself.

Have you actually tried this yet? Because cy.request already sets the User Agent of the browser you're running. In other words - it'll look pretty damn close to what naturally comes from the browser anyway.

Still facing this issue with version 2.1.0.

You may only visit a single unique domain per test.
Different subdomains are okay, but unique domains are not.

The previous domain you visited was: 'https://single-signon.corp.company.com'
You're attempting to visit this new domain: 'https://app-host.company.com'

Still facing this issue with version 3.3.1.

CypressError: cy.visit() failed because you are attempting to visit a second unique domain.
You may only visit a single unique domain per test.
Different subdomains are okay, but unique domains are not.
The previous domain you visited was: 'http://azureinteractives.azurewebsites.net/'
You're attempting to visit this new domain: 'https://vsfutures.azurewebsites.net/'
You may need to restructure some of your code to prevent this from happening.
