dokumentrotkataloger

A dokumentrotkatalog, or document root directory, is a crucial concept in web server configuration. It is the directory on the server where the web server looks for files to serve when a user requests a webpage. When a web browser requests a URL, the web server translates that URL into a file path on the server's file system. The document root defines the starting point for this translation.

For example, if a user requests "http://www.example.com/index.html", and the document root for "www.example.com" is set to "/var/www/html", the web server will look for the file "index.html" within the "/var/www/html" directory. If the request was for "http://www.example.com/images/logo.png", the server would search for "logo.png" inside the "images" subdirectory of the document root, i.e., "/var/www/html/images/logo.png".

The document root is typically configured in the web server's configuration files, such as Apache's httpd.conf or Nginx's nginx.conf. It is essential for security to ensure that the document root is set correctly to prevent the web server from serving files outside of the intended web content. Incorrectly configured document roots can expose sensitive system files or directories. Many web hosting providers pre-configure a default document root for their users.
