Where can I check the value of $Setup variables?

Question

I have this code:

<link rel="canonical" href="{!$Setup.websiteSystemVariables__c.Main_URL__c+$CurrentPage.Name}"/>

I want to check where the $Setup.websiteSystemVariables__c and $CurrentPage.Name values are coming from.

When I view the page source, they are evaluated as:

<link href="xyz.comhomepageAB" rel="canonical" />

But I want to add a backslash between URL and page name like this URL:

 <link href="xyz.com/homepageAB" rel="canonical" />

I researched classes, components but I m not able to solve this... Thanks !!

Answer 1

You can just concatenate the slash character in the merge syntax:

<link rel="canonical" href="{!$Setup.websiteSystemVariables__c.Main_URL__c + '/' + $CurrentPage.Name}"/>
