Issue/Introduction

Whenever browsing a blocked HTTPS/SSL website via Unified Agent, the browser does not display the exception page. Instead, the browser displays a pop-up notification message on the taskbar, as follows:



In this example, the message states that the HTTPS request is blocked for site https://www.facebook.com.

This behavior is by design. The HTTP GET request is encrypted and Unified Agent is unable to perform the redirect.
