Preparations

1. in the /index.php file replace $application->Run(); line with this:

define('DBG_SKIP_REPORTING', 1);
echo $application->HREF('platform/my_account/my_account') . PHP_EOL;

2. create /test.http file with this content (replace path/to/in-portal/ with domain & path to In-Portal installation, but keep protocol as-is):

### HTTPS to HTTP
GET https://path/to/in-portal/
Nginx-Proto: http

### HTTPS to HTTP
GET http://path/to/in-portal/
Nginx-Proto: http

### HTTP to HTTPS
GET http://path/to/in-portal/
Nginx-Proto: https

### HTTPS to HTTPS
GET https://path/to/in-portal/
Nginx-Proto: https

### As-is HTTP
GET http://path/to/in-portal/

### As-is HTTPS
GET https://path/to/in-portal/

Test

1. open /test.http file in the PhpStorm
2. run each of 6 tests (each will output the URL to the My Account page)
3. confirm, that:
   • tests that have a Nginx-Proto header would use the provided protocol in the resulting URL
   • tests that don't have a Nginx-Proto header would use protocol from the visited URL in the resulting URL
