How to find which php is redirecting?

Question

PHP

Bitra runs on nginx+php-fpm.
Somewhere in her instance there is a redirect of urls from uppercase to lowercase. I already found out in my previous question here that there are no redirects in the nginx settings for this. That is, the point is somewhere in php (or js) bits.
How can I find which php file is responsible for this? What occurrence to look for in the code?

If the matter is in Bitrix, then you need to look for calls to the LocalRedirect function . Add logging to the body of the function (writing to the debug_backtrace output file).
LocalRedirect is declared in the bitrix/modules/main/tools.php file
