File URL

The last section of a URL specifies what individual file/object to open on the web server.

File/Folder Names:

The File URL typically includes the name(s) of the folder(s) under which the file is located and then the name of the file itself.

Example:

company/contact-us.html

In this example, the File URL specifies that you should open the contact-us.html page in the company folder.

File Extensions:

There are many ways to identify a file on a web server depending on how the site's administrator and/or the content management system functions. The most common method to identify a web page type is by giving it an extension of .html.

Common file name extensions:

.html - A basic web page

.shtml - A web page that uses server side includes

.pl - A web page that is processed with the Perl programming language

.cgi - A web page that is typically processed with the Perl programming language

.php - A web page that is processed with the PHP programming engine

.asp - A web page that is processed with Microsoft's active server pages engine

.aspx - A web page that is processed with Microsoft's .net technology

.cfx - A web page that is processed with Adobe's Cold Fusion engine

Note: These extensions are specific to special programming languages that could be used on the web server hosting a website. Website administrators can use these default extensions for the programming language they are employing, or they can use any other extension of their choice (including no extension at all).
