Disable SSL interception for single URL

Products

• Advanced Secure Gateway Software - ASG
• ProxySG Software - SGOS

Issue/Introduction

SSL interception can be disabled for a single URL/Domain using CPL or VPM policy if the deployment is explicit. In a transparent deployment, SSL can be disabled using server certificate and not destination URL as mentioned in How to bypass SSL based on server certificate.

This will not disturb SSL interception for other URLs or Domains.

1. Log in to the Management Console (https://<IP_address>:8082).
