Code for this available on: https://github.com/jenkinsci/blueocean-plugin/pull/1658

As suggested by Daniel Beck, it would be a good idea if blue ocean had a jenkins config setting that made the home page default to /blue (Tyler has done this with nginx rules before). 

This is a necessary precursor to making blue the default out of box experience/entry point, allowing people to opt in. 

In scope: 

• When set, accessing the root will redirect to /blue
• Existing links back to classic will keep working
• Configured in settings, but also via system property/env variable (off by default initially)

Testing: 

• Should be tested via ATH in blue ocean
• Need to ensure that links back to classic are not broken and "cool urls don't change"
• Ensure only links to root redirect to /blue
• Ensure that there are not any side effects (people using queries against root, for example) - investigation needed here.
