---------------------------------
Summary: SHS links sometimes broken on FINISHED jobs page
Key: KNOX-2456
URL: https://issues.apache.org/jira/browse/KNOX-2456
Project: Apache Knox
Issue Type: Bug
Affects Versions: 1.4.0
Reporter: Iain Buclaw
For unexplained reasons, most of the time SHS links are in the format
`http://host:port/proxy/application_123_456`, but sometimes they can be
`/proxy/application_123_456`.
This causes broken URLs on the page, along with the following logged error.
