server variable typically stores the hostname of your site. It is commonly used in report suites that contain data from multiple domains. It is functionally identical to a prop.
You can set server either while configuring the Analytics extension (global variables) or under rules.
You can set server to any string value or data element.
s.server variable is a string that typically contains the hostname of your site. It has a maximum value of 100 bytes; longer values are truncated.
// Set the server variable to a static string s.server = "Example server"; // Automatically set the server variable to the site's hostname s.server = window.location.hostname;
