(Pathauto: Leave case the same as source token values)
When I create a node with "Nullam vehicula pharetra" as title, the Pathauto module will create /content/Nullam-vehicula-pharetra as URL alias. But we can browse the same content with a different URL case, such as /content/NULLam-vehicula-pharetra.
How do I make Drupal strict on the URL alias case?
Wikipedia is good example about what I need. Two different case request return different contents:
Even if you don't use pathauto, Drupal7 can not differentiate case sensitive urls. This 'issue' is not code related, but it has to be with the database collation. non-binary string comparison are case-insensitive by default.
A solution could be to set the 'alias' columns (menu_router.path, url_alias.alias) to binary (case-sensitive).
Be aware that changing the structure of those two columns in existing sites could result in broken links because paths/alias would have to match base on case.
I agree with Blanca.
Wikipedia, and wikis in general, use a completely different system of creating and linking pages.
The following doesn't answer your question but it might help with your approach.
To avoid search engine ranking issues I always select "Change to lower case" in /admin/config/search/path/settings, as well as use Global Redirect with "Case Sensitive URL Checking".
So if a you visited domain.com/Page you'd be redirected to domain.com/page.
This seems like a more logical approach to me. I don't think any user would expect to see different content according to case sensitivity. i.e. to take this a step further StackExchange.com is no different to stackexchange.com.
Of course, in your case, this might not make any sense.
