Incorrect redirect to malformed url within AUT - adding `_/` in url

Current behavior:

When I instruct cypress to login to an Oracle APEX application, the authentication re-directs cypress to a ‘404 not found’ page because the authenticated URL is malformed. The malformed URL is the only issue and can simply corrected programmatically (with a find and replace command).

However - it is very important to note that the cypress login correctly returns:

1. a valid cookie
2. a valid session

which is everything you need for authentication.

Desired behavior:

Cypress, ideally, should be able to follow the same authentication redirect that a user would in a regular browser.

Steps to reproduce: (app code and test code)

I created a dummy application with dummy credentials hosted by apex.oracle.com to demonstrate:

it('Login demo', function() {
    cy.visit('https://apex.oracle.com/pls/apex/f?p=54707:LOGIN_DESKTOP')
    cy.get('#P9999_USERNAME').type('ApexUser')
    cy.get('#P9999_PASSWORD').type('Oradoc_db1')
    cy.get('.t-Button').click()
  })

The above code (which should work until the application expires in many months) will redirect to a 404 not found page with a url in the format: https://apex.oracle.com/__/f?p=54707:1:[session_id]::::: Outside of cypress the url will have the format: https://apex.oracle.com/pls/apex/f?p=54707:1:[session_id]:::::

Versions

I have tested this across 4 instances of Oracle APEX (APEX 5.0, 5.1, 18.1 and 19) and this behavior is consistent.

I am also facing this issue with all browsers including Electron :

• Electron
• Edge 85 (85.0.564.41)
• Chrome 85 (85.0.4183.83)
• Firefox 80 (beta)

Cypress 4.7.0 Node v8.11.3

Same after upgrading to latest versions: Cypress 5.1.0 Node v12.18.3

it('Login page', () => {

        // visit main home page
        cy.visit('https://tstapex.myhost.ch/ords/f?p=119')

        // make sure we are redirected to login
        cy.url().should('include', 'LOGIN_DESKTOP')

        // log in
        cy.get('#P9999_USERNAME').type('username')
        cy.get('#P9999_PASSWORD').type('password')

        // click login button
        cy.get('#login-button').click();

    })

I’m redirected to https://tstapex.myhost.ch/__/f?p=119:1:28275213605974:::::

Then of course get:

Not Found The requested URL /__/f was not found on this server.

Setting experimentalSourceRewriting to true does not help.

There is an open PR meant to fix this here: https://github.com/cypress-io/cypress/pull/5273 It’s complicated and is still a work in progress.
