=== Concept: Paths, Aliases, and URLs

(((Paths, Aliases, URLs, overview)))

//==== Prerequisite knowledge


==== What is a URL?

URL is an abbreviation of "Uniform Resource Locator" and is the page's address on the web. It is the "name" by which a browser identifies a page to display. In the example "Check us out at farmersmarket.com." the part farmersmarket.com is the URL for the home page of your web site. Users use URLs implicitly to locate content on the web.

==== What is a Path?

Drupal uses "nodes" to identify pages by their position in your database. So the “About Us” page on your farmers market site might be known as "node/167." to Drupal. By maintaining the list of nodes in your site, the URLs are maintained as a result, which in turn enables your visitors to find your site's content.

==== What is an Alias?

Drupal has a feature called "URL Alias" that allows you to provide a more understandable name to the content. As far as browsers, servers, and search engines go, it is totally unnecessary. But for humans, it is nearly mandatory. This is why most consultants tell people to always turn on the Path core module, which supports URL aliasing.

So, just before you submit your “About Us” page, and if you have the Path module enabled (and you will want it), then you'll see a section on the edit page that says "URL path settings." So let's say you want your visitors to see it as http://www.farmersmarket.com/AboutUs. In the URL field, enter AboutUs.

You can administer the URL Aliases directly on the node edit or add forms, or by doing the following:

First, visit the page you created. In your browser's address field, you'll see its URL. On the end it will probably say "node/xxx" where xxx is some number. Write down that number.

Now go to:
Configuration > Search and Metadata > URL Aliases 

There's an "Add Alias" tab at the top. In the top box, enter "node/xxx" from above. In the second box, enter "AboutUs".

If your site is going to have lots of content, particularly user-submitted content, you might want to look at the https://www.drupal.org/project/pathauto[PathAuto module]. Not only will this module automatically generate URL aliases for new content (according to rules you can set up), but can even go back and change aliases in bulk.
