Webserver directory index
*** Shopping-Tip: Webserver directory index
When an
HTTP client (generally a
web browser) requests a
URL that points at just a
directory (computing) rather than at a
directory (computing) rather than at a
file within a directory the
web server will generally serve up some kind of main or index page.
index.html is the traditional filename for such a page, but most decent webservers will allow a list of filenames to be configured. If a server is set up to support
server-side scripting then there will usually be entries in the list to allow dynamic content to be used as the index page (for example: index.
php, index.
shtml, default.
Active Server Pages). In the popular
Active Server Pages). In the popular
opensource_web server
Apache web server the list of filenames is controlled by the DirectoryIndex directive in the configuration file.
If the webserver cannot find a page with any of the names its set to try then it may either return an error (generally
404 (Not Found) ) or create its own index page of the files in the directory. This is usually also a configuarable option.
In order to allow relative links to work correctly the URL for a directory must end with a slash. If it does not then most webservers will send a
http redirect to add the slash.
http://www.mysite.tld is not really a valid url but almost all browsers will turn it into
http://www.mysite.tld/ automatically and this will then result in the serving up of the index page from the root directory of the website.
