title: How to link to another liferay page
body: <p>I'm trying to figure out how to link to another page within the same liferay site. </p>
  
  <p>Obviously I could hardcode the url in my portlet's view but I'm worried about having to update all of my portlets in case the friendly url changes in the future.</p>
  
  <p>I know the name of the page I'm trying to link to, but what if the page name changes too?</p>
  
  <p>I've found infinity of classes that have methods that return friendlyUrls, such as <code>PortalUtil</code>, <code>LayoutLocalServiceUtil</code>, and even <code>LayoutFriendlyURLLocalServiceUtil</code>, but they all require parameters that I'm not sure how to obtain.</p>
  
  <p>Is there a standard way of obtaining friendly urls in liferay?</p>
