Note: Horizon Web Client is available with Horizon 8 versions 2412 and later. For Horizon 8 versions 2406 and earlier, Horizon Web Client is called "HTML Access." This documentation page uses the name "Horizon Web Client" to refer to both Horizon Web Client and HTML Access.
Set an allowlist to restrict user agents that can interact with Horizon 8. You can do this by adding your entries to the locked.properties file then restarting the Secure Gateway service. By default, all user agents are accepted.
Note: This is not strictly a security feature. User agent detection relies on the user-agent request header provided by the connecting client or browser, which can be spoofed. Some browsers allow the request header to be modified by the user.
A user agent is specified by its name and a minimum version. For example:
clientWhitelist-portal.1 = Chrome-14
clientWhitelist-portal.2 = Safari-5.1
This means that only Google Chrome version 14 and later, and Safari version 5.1 and later are allowed to connect using Horizon Web Client. All browsers can connect to other services.
You can enter the following recognized user agent names:
- Android
- Chrome
- Edge
- IE
- Firefox
- Opera
- Safari
Note: Not all of these user agents are supported by Horizon 8. These are examples.
