I have new server with IIS 10 and PHP on it (FastCGI). When I type full address (e. g. domain.com/index.php) everything is fine. But when I'm using short address (only domain.com) browser trying to download file without name (but when I save it, it is my index.php) - not executing PHP.
Have anyone idea why? Where can I search reason of this?
Check <defaultDocument> element on ApplicationHost.config file. If "index.php" is not included add it.
