Is this a Joomla! Issue? What happens if you access a live page then capitalise one letter?

Traditionally the urls are case sensitive unless a module has been installed on the server to stop case sensitivity on urls.

I have the same problem. According to the (forum)[https://forum.joomla.org/viewtopic.php?t=932554], other people are having the same issue also.

1. Create URL redirect with source url in lower case (e.g. http://mysite.com/test
2. Type in a capital version of the url in the browser (e.g. http://mysite.com/Test

Result: 404 page

Expected Result: redirect to destination url

To answer tonypartridge, changing case on an existing page does not result in 404. Only fails if redirect source urls have incorrect case.

I would love to help code a solution if someone can just point me in the right direction.

I believe that the problem is:

1. A redirect source url is created http://mysite.com/test
2. Visitor enters http://mysite.com/Test in the browser (uppercase used)
3. The database is queried for a matching redirect using a case sensitive parameter (fails)
4. The page is redirected to a 404 page because the redirect plugin did not find a matching redirect source url

I believe the solution is to correct the visitor's query to match a non-case sensitive redirect source url.

My question: What file controls the visitor's query to check if the source redirect exists?

Would it be plugins/system/redirect/redirect.php?

Thanks!

Note: using Joomla 3.6.5

Nope - scratch that. I queried the database using both uppercase and lowercase and still retrieves the set. The collation is set to utf8mb4_unicode_ci so the row is case insensitive (_ci). I don't know... Maybe something with the url mapping?

@dmurphy779 leave it with me, It's in the plugin but I need to validate my fix before submitted a PR.

PR is: #13853

Thanks Tony!
