- Cisco Employee,
Cisco is pleased to announce a maintenance release of AsyncOS 6.3.1-028 for Web to all customers (GA).
This release applies to all our Web Security Appliances (S-Series).
This new build addresses two severe defects that have been found in the former 6.3.1-025 GA release.
We encourage you to upgrade to this new build to benefit from the enhanced stability in 6.3.1-028.
Enhancements and Fixes in AsyncOS 6.3.1-028 for Web
- Fixed: Some transparent HTTPS requests erroneously bypass all Routing Policies
and go directly to the Internet. [Defect ID: 55596]
Previously, when Routing Policy membership depended on data in a request header,
such as the URL, then transparent HTTPS requests failed to match the Routing Policy.
Instead, they were routed directly to the Internet. This no longer occurs.
Now, those transparent HTTPS requests match the Default Routing Policy.
- Fixed: Web Proxy generates a core file and restarts in some cases. [Defect ID: 65975]
Previously, the Web Proxy generated a core file and restarted when repeatedly connecting to
servers that delivered 503 Bad Gateway responses to the Web Proxy. This no longer occurs.
