This page is showing a generic answer. To see a more detailed answer customized for you, type your domain name here:. An "index page" is the Web page that appears when someone visits the top level of your website or a directory within the site without specifying a particular file name.
The way a Web server chooses a default page to display is simple: When it receives a request that doesn't include a file name, it consults a list of default file names such as " index. That means that if you have a file named " index. Both addresses display the file named " index. The first does so because the server invisibly to the visitor looks through a list of default file names and finds a file matching one of those names index. The file must be at the top level; the Web server won't be able to find the file if it's inside a folder or directory you published.

Whenever you have a directory on your website, it is a best practice to have a corresponding index.
Even if you do not plan to display content on the index pages of select directories with any actual page links, having the file in place is a smart user experience move, as well as a security feature. Most web servers start out with the directory structure visible when someone comes to a directory without a default file.
This view shows them information about the website that would otherwise be hidden, such as directories and other files in that folder. This transparency can be helpful during a site's development, but after a site is live, allowing for directory viewing can be a security vulnerability.
If you don't put in an index. While this behavior can be disabled at the server level, it means that you need to involve the server admin in order to make it work. IIS installations have directory browsing disabled by default. If the default document is not found and both default document and directory browsing is disabled, the user will get a error.
If you are pressed for time and want to control this on your own, an easy workaround is to simply write a default web page and name it index. Uploading that file to your directory will help close that potential security hole. Additionally, it is also a good idea to also contact your hosting provider and ask for directory viewing to be disabled. Some websites, like those that are powered by a content management system or ones that use more robust programming languages like PHP or ASP, may not use.
For these sites, you still want to ensure that a default page is specified, and for select directories in that site, having an index. Actively scan device characteristics for identification.
