CakePHP controller , Url not found on server

Question

I write a controller in CakePhp-2.9 named API to access outside. Controller Code:

class APIController extends AppController
{
var $name = 'API';
var $cache_dir = 'img/cache';
var $cache_width = 400;
public $msgs = array();

public function beforeFilter()
{
    parent::beforeFilter();
         $this->Auth->allow('ecall_request','ecall_callback','testlog','ecall_request_test','ecall_callback_test');

} 


public function ecall_request()
{   


Cache::write("test_request".time(),$this->request->data);
if($this->request->is('post'))
{
 // my code here
}
 }
}

And i tested "http://localhost/dentech/api/ecall_request" on POSTMAN successfully, But when i upload it on server at https://dentech.com/api/ecall_request it does not access and gives 404 error.

htaccess code is:

<IfModule mod_rewrite.c>
RewriteEngine on
# Uncomment if you have a .well-known directory in the root folder, e.g. for the Let's Encrypt challenge
# https://tools.ietf.org/html/rfc5785

RewriteCond %{HTTPS} off
 RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

#RewriteRule ^(\.well-known/.*)$ $1 [L]
RewriteRule ^$ app/webroot/ [L]
RewriteRule (.*) app/webroot/$1 [L]

Updated from comments: The reason for the 404-error is that the controller name in the URL has to be in uppercase characters. Instead of

https://dentech.com/api/ecall_request

You need to use

https://dentech.com/API/ecall_request

The fact that it works on localhost but not on the server is the difference in the operating system. Windows (often used locally) is not case-sensitive, while Linux (usually the servers OS) is case-sensitive.
