1.     Create a new rule in a Web Access Layer. Set the Action to Deny.

2.     In the Destination column, create and set a new Request URL object. Specify the following:

   • Select Advanced Match.

   • Set the Host to LinkedIn and change the drop-down to Contains and Set the Path to voyager and set the drop-down to Contains

3. In the Service column of the rule create a new Protocol Method object. Specify the following:

   • Set the Protocol to HTTP/HTTPS.

   • Select POST and Click OK.

4. Install the policy.

 

Note: The Possibility exists that in future Linkedin updates may break this rule. You can find the URL and apply the same logic. This word under "Path" is taken from a Policy trace. We have taken a policy trace and identified which request triggers LIKE. You can find this information by using the developer tool in your browser too. The URL which triggers for LIKE is "https://www.linkedin.com/voyager/api/feed/likes". Simply leaving it as voyager may block other Linkedin functionalities.
