Using the WebSocket API (WebSockets), you can send messages to a server and receive responses without polling the server for a reply. To allow WebSockets to work, you must exempt it from HTTPS inspection.
- Create a Custom Category.
- Add trusted domain or subdomain sources that use WebSockets to the Domain/URL filtering section.
- If the domain or subdomain is not static, use a URL pattern instead. Contact Smoothwall Support for help with configuring this.
- Create a HTTPS Inspection Policy for the category to Do not inspect.
- Move this policy above any HTTPS Inspection Policies that Decrypt and Inspect everything.
