# Manage Cross Sub-Domain Flows

A subdomain is a part of a domain that is located before the domain name and separated by a dot. Subdomains are also commonly used to separate a section of a website from the main site. For example, in the URL http://docs.google.com, docs is the subdomain of the Google domain.

Generally, session storage is typically limited to a specific subdomain, meaning that data stored in session storage on one subdomain cannot be directly accessed from another subdomain. For example, if a Flow has steps 1, 2, 3 on support.whatfix.com and steps 4, 5, 6 on about.whatfix.com, when a user navigates from one subdomain to another, the session storage limitations can cause issues such as loss of Flow information or Flow failing.

When you enable **Handle Subdomain**, Whatfix manages cross subdomain flows. So, even if a Flow spans across multiple subdomains, Whatfix ensures that the Flow information is managed effectively, bypassing the domain-specific constraints of session storage.

Use the following steps to manage cross sub-domain Flows:

1. On the Whatfix Guidance dashboard, click **Settings**. ![ia_left_nav_settings](https://cdn.document360.io/a268766e-d74d-4619-9613-e2472f809ffb/Images/Documentation/ia_left_nav_settings.png)
