Wondering if it's possible to implement in IIS10 actions similar to those provided by mod_alias for Apache, specifically "Alias" to map a filename from an HTTP request to a common local path outwith that site's DocumentRoot or Physical Path rather than rewriting to an alternative location within the site or redirecting to another URL.

In Apache I have an "Alias" declaration configured at the global level:

Alias /contact.php "/var/www/contact.php"

This declaration is inherited by each VirtualHost (site definition) so that a call to "/contact.php" at any site (e.g.: https://example.com/contact.php etc) will cause the single common file "/var/www/contact.php" to be processed.

The configuration as described above simplifies site management since it is not necessary to deploy and maintain a duplicate file across multiple Web site content directories.

Is there a way to mimic this in IIS10?

I have looked at URL rewrites, application and virtual directory definitions among others and have been unable to find a configuration which exactly meets the requirement.

TIA
