#10879 made it possible to create a partial URL in the Location HTTP-header for redirects. This yields a correct Location HTTP-header as long as server.servlet.context-path is not set. However, if server.servlet.context-path is set, then the context-path is not included in the Location HTTP-header which is incorrect and prevents the clients from following the redirect.

Task List

• Steps to reproduce provided
• Stacktrace (if present) provided
• Example that reproduces the problem uploaded to Github
• Full description of the issue provided (see below)

Steps to Reproduce

1. Create a new Grails app
2. Set server.servlet.context-path to e.g. "app" in application.yml
3. Create TestController and OtherController
4. Let TestController redirect to OtherController: redirect(absolute: false, controller: 'other') and let OtherController render some text.
5. Start the app and call TestController with curl: curl -iL http://localhost:8080/app/test

Expected Behaviour

Expected text response from OtherController after redirect. Location HTTP-header should be: http://localhost:8080/app/other

Actual Behaviour

Gets HTTP-status 404, because Grails does not add context path to the partial Location HTTP-header. Location HTTP-header was: http://localhost:8080/other

Environment Information

• Operating System: Ubuntu 20.04
• Grails Version: 4.0.6
