What does this MR do and why?

It re-introduces case sensitive pages URLs.

How to set up and validate locally

  1. Make sure you have set up Runners and Pages.
  2. Enable access control for Pages: https://docs.gitlab.com/ee/development/pages/#enabling-access-control
  3. Create a new private Pages project by using the Pages/Plain HTML template. Use a project path containing capitals, but no hyphens -, e.g. (MyHTMLProject, but not My-HTML-Project). Make sure to input the project path manually, because the default behaviour is to generate a slugified version of the project name (lowercased and hyphenated).
  4. Go to the projects "Settings>General", expand "Visibility, project features, permissions" and set "Pages" to "Only Project Members".
  5. Under "Build>Pipelines" Run the project's pipeline manually.
  6. Go to "Deploy>Pages" and uncheck "Use unique domain". Reload the page.
  7. Copy the link shown under "Deployments" and open it in a private window. Make sure it contains the capitalisation used in step 3 as the project path.
  8. In the new window, you should see a login screen. After successful authentication the pages site should be visible.
