Use cases for generated urls in symfony2?

Based on direct PHP and the Drupal background, I recently learned the structure of Symfony2. I am currently in the book routing chapter. This is probably a simple question.

What are some real world use cases for why you would need to create URLs in a Symfony application? I understand the code, but I had problems defining its practical applications. p>

I mean this section if you need to update.

Thanks as always!

PS The symphony is awesome. :)
