Replace slashes with dot to load correct configuration file if the website loads via reverse proxy

[devendrabhandari]

Description

Remove trailing forward slashes and backslashes if they exist and then replace slashes with dot.

Type of change

Bug fix (non-breaking change which fixes an issue)

Is the solution different from the one proposed during the grooming?

No grooming as it's a very small change.

How Has This Been Tested?

If the HTTP_HOST is www.example.com/blog/ then WP Rocket try to load the configuration file from www.example.com%2Fblog.php instead of www.example.com.blog.php.
