 The port number is checked separately by the browser. Any call to `document.domain`, including `document.domain = document.domain`, causes the port number to be overwritten with `null`. Therefore, one **cannot** make `company.com:8080` talk to `company.com` by only setting `document.domain = "company.com"` in the first. It has to be set in both so their port numbers are both `null`.

 > [!NOTE]
 > When using `document.domain` to allow a subdomain to access its parent, you need to set `document.domain` to the _same value_ in both the parent domain and the subdomain. This is necessary even if doing so is setting the parent domain back to its original value. Failure to do this may result in permission errors.
