Re-Enabling document.domain Injection
As of Cypress v14.0.0, document.domain
will no longer be injected into text/html pages by default.
This means you must now use cy.origin() when navigating between different origins
in the same test. Previously, cy.origin() was only necessary when navigating between
different superdomains in the same test.
By setting the injectDocumentDomain configuration option to true, Cypress will
attempt to inject document.domain into text/html pages.
A superdomain is comprised of the trailing two elements of the hostname, delimited by
a . (period). Given https://www.cypress.io, the superdomain is determined to be
cypress.io. When this option is enabled, cy.origin() is not necessary when navigating
between https://www.cypress.io and https://docs.cypress.io, but is necessary
when navigating between https://www.cypress.io and https://www.auth0.com.
- This will cause issues with certain sites, especially those that use origin-keyed agent clusters.
- This option is deprecated, and will be removed in a future version of Cypress. :::
