Cookie settings for accessing on-premises applications in Azure Active Directory
Azure Active Directory (Azure AD) has access and session cookies for accessing on-premises applications through Application Proxy. Find out how to use the Application Proxy cookie settings.
What are the cookie settings?
Application Proxy uses the following access and session cookie settings.
|Use HTTP-Only Cookie||No||Yes allows Application Proxy to include the HTTPOnly flag in HTTP response headers. This flag provides additional security benefits, for example, it prevents client-side scripting (CSS) from copying or modifying the cookies.
Before we supported the HTTP-Only setting, Application Proxy encrypted and transmitted cookies over a secured SSL channel to protect against modification.
|Use Yes because of the additional security benefits.
Use No for clients or user agents that do require access to the session cookie. For example, use No for an RDP or MTSC client that connects to a Remote Desktop Gateway server through Application Proxy.
|Use Secure Cookie||No||Yes allows Application Proxy to include the Secure flag in HTTP response headers. Secure Cookies enhances security by transmitting cookies over a TLS secured channel such as HTTPS. This prevents cookies from being observed by unauthorized parties due to the transmission of the cookie in clear text.||Use Yes because of the additional security benefits.|
|Use Persistent Cookie||No||Yes allows Application Proxy to set its access cookies to not expire when the web browser is closed. The persistence lasts until the access token expires, or until the user manually deletes the persistent cookies.||Use No because of the security risk associated with keeping users authenticated.
We suggest only using Yes for older applications that can't share cookies between processes. It's better to update your application to handle sharing cookies between processes instead of using persistent cookies. For example, you might need persistent cookies to allow a user to open Office documents in explorer view from a SharePoint site. Without persistent cookies, this operation might fail if the access cookies aren't shared between the browser, the explorer process, and the Office process.
Set the cookie settings - Azure portal
To set the cookie settings using the Azure portal:
- Sign in to the Azure portal.
- Navigate to Azure Active Directory > Enterprise applications > All applications.
- Select the application for which you want to enable a cookie setting.
- Click Application Proxy.
- Under Additional Settings, set the cookie setting to Yes or No.
- Click Save to apply your changes.
