What are URL path aliases and why do we need them?
When you create a page in Drupal (the web editor we use to manage our web pages,) the system assigns your page (or node) a number automatically. This page has a node number of 745 for example, and you can access it by going to /infotech/node/745. But that's not very easy to remember and we humans prefer a more practical way to reference our pages. The URL alias accomplishes that task very well.
On the bottom of the create/edit section of your page is a link titled: "URL path settings." When you click on it, and new set of options will appear:
Now whatever you type here will replace the "node/745" in the URL. For example, you can reference this page without an alias at /infotech/node/745 or with the alias: /infotech/web/aliases.
TIP: We chose to organize all of the Web Services' pages under web/* aliases. You may want to organize the sub-sections of your site similarly as well.
