Canonical and None URL mappings don't work correctly on localized sites

[daguiler]

Description of bug

Canonical and None URL mappings don't work correctly on localized sites. This is pretty much what #3017 is about, but steps to reproduce are more precise.

Steps to reproduce

1. Set up a new IIS web site for DNN 9.4.3. Name it platform-9-4-3.dnndev.me.
2. Install DNN 9.4.3 with default settings (as in /install.aspx).
3. Add non primary alias www-platform-9-4-3.dnndev.me (and corresponding IIS binding)
4. Ensure URL Mapping is set to Canonical
5. Add French as a second language
6. Enable content localization, create localized pages, mark all as translated, activate French pages, publish all French pages.
7. Create additional non-primary aliases:
   7.a) www-platform-9-4-3.dnndev.me/en-us for English
   7.b) www-platform-9-4-3.dnndev.me/fr-fr for French
8. Navigate to www-platform-9-4-3.dnndev.me/fr-fr/

Current behavior

DNN redirects to platform-9-4-3.dnndev.me/fr-fr (the primary alias)

Expected behavior

Given URL mapping is set to canonical, no redirection should be performed.

Additional context

Some pitfalls with Chrome:

• Chrome hides "www." prefix from the URL, which can be very confusing. That's why I used "www-" (with a dash) to avoid this.
• Keep the Dev Tools panel open at all times with the cache disabled. This will get rid of confusing caching issues.

Affected version

• 10.0.0 alpha build
• 9.5.0 alpha build
• 9.4.x latest supported release
• 9.3.x latest supported release
  (not sure about older versions)

Affected browser

N/A

@daguiler is this exactly the same as #3017 ? Should we add these steps to the existing issue instead of duplicating it ?

[daguiler]

Hi @valadas, yes, same issue. Since there is no discussion yet on #3017, I thought maybe it would be cleaner to start from scratch, but I'll leave it up to you. I'm about to submit a PR about this.
