Using Distributed Configuration Files (.htaccess)
Distributed configuration files are used to make directory-based changes to the HTTP Apache Server configuration and usually have the name .htaccess.
If you are using a file with the name .htaccess, IntelliJ IDEA recognizes it as distributed configuration file and provides full coding assistance for it, so no additional steps are required from your side.
If you want to use a file with another name, you need to associate this full name or the corresponding pattern with the distributed configuration file type. After that, IntelliJ IDEA will treat any file with the name matching the specified pattern as a distributed configuration file and process it accordingly.
Associate a name pattern with the distributed configuration file type
Select Apache Config from the Recognized File Types list.
In the Registered Patterns area, click .
In the Add Wildcard dialog that opens, specify the pattern that defines the extensions of your distributed configuration files.
Click OK. IntelliJ IDEA returns you to the File Types page where the specified pattern is added to the Registered Patterns list.
To discard a pattern, select it in the list and click .
To change a pattern, select it in the list, click , and update the pattern as necessary in the Add Wildcard dialog that opens.
