How to make links lowercase in yii?

Question

Yii

Hello!
How to make links in lowercase work in yii?
now the pages are opened at the addresses site.ru/category1 and site.ru/category2
at the same time, if you follow the link site.ru/category1 gives a 404 error
(and can some server settings affect this?)

Answer 1

As I understand it, alias is stored in the database, you make a request in the action and return a 404 error if not found. So the solution is right there, in the action. It is necessary to make a case-insensitive query in the database. Config and urlManager have nothing to do with it.
