아파치 DocumentRoot and Alias Conflict
Setting an Alias to the root directory (/) within the DocumentRoot might lead to conflicts or errors because the root directory is already serving as the base directory for the VirtualHost. By setting an Alias to the root directory, you essentially redefine the root directory itself, which can cause confusion for the server.
Here's why it may cause an error:
Conflicting Definitions: When you set an Alias to /, you are essentially telling Apache to map the root URL (/) to another directory. This conflicts with the default behavior of Apache, which already serves content from the DocumentRoot for requests to the root URL.
Infinite Loop: If you set an Alias to / pointing to the DocumentRoot, it can create an infinite loop or redirect loop. Every request to the root URL would be internally redirected to the same root URL, resulting in an infinite loop.
Invalid Configuration: Apache might interpret such a configuration as invalid or ambiguous, leading to errors or unexpected behavior.
To avoid these issues, it's best to avoid setting an Alias to the root directory (/). Instead, use Alias to map specific URLs to different directories within or outside the DocumentRoot, as needed for your application or website.
